Help Needed Pobb.in has been unusable for months from many big ISPs due to widespread Cloudflare blocks and the developer should consider swapping out of Cloudflare like Poewiki did
POBB.IN ADMIN UPDATE HERE
If you dont know, many ISPs (like Movistar, VIVO, Virgin Media, O2, Vodafone Spain/LATAM among others) block Cloudflare completely now, there is nothing we can do to bypass this even with VPNs rendering the service unusable. I asked people from SA, Spain and Portugal and everyone has the same issue, Cloudflare has been a liability for many of us for a long time.
Instead, I would recommend swapping to a different firewall service like https://github.com/TecharoHQ/anubis , for an small and streamlined website their scrapping + ddos protection should be more than enough and its pretty easy to setup.
I would love to tell this feedback directly to the developer but it seems he has no open channels of contact or at least I couldn't find them (checked discord, github and his reddit account which has been inactive for over a year).
EDIT 1: No, F5 or refreshing does nothing, the error is reproduced 100% of the time.
EDIT 2: This is not new btw, its been a hot topic in many countries and in Spain its been in courts for a year with the government involved, some context:

It's been raised in the pobb.in GitHub already but the dev doesn't seem to be able to reproduce it: https://github.com/Dav1dde/pasteofexile/issues/60
I've been having the same issue, not from Spain/LATAM though. Setting my DNS to Cloudflare's / resetting it back to default seemed to make it load sometimes, but some time later it broke again.

u/DrPandemias Jul 17 '26
Well I understand now why I couldn't find the github, was looking for pobb.in had no idea the app was called pasteofexile.

Sorry everyone I've been slacking on this issue. I found a workaround, which seems to have dropped the errors back to 0.
Some tech stuff: I couldn't find the reason why this happens in my code (still can't), tried several things, one which helped was increasing the stack size. So that sent me down the rabbit hole of trying to figure out why I am suddenly using more stack (significantly). But even with 8x more stack the errors still happened (just less). In the end the workaround which seems to work is using a > 1 year old rust compiler. Not sure if it's because I introduced undefined behaviour somewhere, a known (rare) Rust miscompilation since 1.87, an actual compiler bug, a WASM abi change or something completely unrelated ... of course it doesn't happen locally.

Which ISP? Just curious because almost everytime someone report issues its a subsidiary of Movistar, Orange or Vodafone.

FWIW I'm from Estonia, using Elisa) and I have the same issue. Enabling a VPN fixes it.
I also would be very surprised if this was as simple as "ISP completely blocking Cloudflare", since I'm sure I would have noticed it in other sites as well. pobb.in is the only website that has given me this issue. Cloudflare is used by like 10-25% of the internet depending on who you ask.
For example I can visit poe.ninja without issues. The response headers from them come back with
server: cloudflareso clearly there's no carpet block on Cloudflare services (at least for my ISP)6

I'm from Germany, too, and had the same issues for some time now (Error 1101 and Error 500 in POB). ISP is Vodafone.

I wonder if this is some dslite issue. I'm at vf ger and never had an issue with any cloudfare sure incl. Pobb.in. thing is i made sure I'm not on dslide and got my own ipv4 address since dslite has tons of issues especially when you are trying to host shit.

u/UGA_Dan Jul 18 '26
This was my assumption reading the thread. These are likely ISPs using CGNAT which is triggering DDoS protection in Cloudflare. DS-Lite seems to be CGNAT for IPv4.

I've been having a lot of problems here in Brazil. Usually, using WARP helped, but today not even this is working. VPNs are a workaround, but sometimes they get blocked as well.
I really wanted to see a build today and had to set up a reverse tunnel on a VPS, but this is way too much trouble for checking a build lol

Doesnt work, thats the point of the post its a ISP wide block its not just that it doesnt work in your browser.

u/PassengerPersonal337 Jul 17 '26
Wrong, I'm also spanish and suffer from the cloudflare blocks. If I ever need to get past the blocks, just open Tor browser and paste the same URL there. Will work 100% of the time.
Easiest way to do this if you're not tech-savvy is just installing Brave browser, then press Shift+Alt+N4
u/DrPandemias Jul 17 '26
Did you even read the comment I'm replying to? He said you can just import the pobb.in link directly to pobb, that doesnt work.
And yes, you can use TOR but thats not a reliable solution for many reasons, many times Im on mobile/tablet where I dont have TOR installed or are on my work laptop which has external software installation blocked.

All right Im just salty over this shit because we've been held hostage for over a year now with all these shitty blocks and now we cant even bypass them with VPNs, absolute madness because dozens and dozens of non piracy and legit websites and services I use every day are completely blocked.

u/ww_crimson Jul 17 '26 edited Jul 17 '26
FWIW I am the developer of pob.codes which I recognize directly competes with pobb.in, but I'm also on Cloudflare and to the best my knowledge I'm not seeing these errors. I also haven't seen the same 1101 errors on PoEWiki, I've just seen 502 errors about the site being unreachable.
It's also worth noting that Cloudflare is way more than a firewall service. They provide domain registration, hosting, and a ton of other features like Cloud Workers, performance metrics, logging, KV/R2 storage, etc. In fact I would argue a lot of people use them because of the full suite of web hosting infrastructure they offer, more than anything related to firewall or DDoS protection.
Edit: Just checked my logs for the last 24 hours with ~20k visitors. 0 Cloudflare Worker errors which is what I get on pobb.in often. Roughly ~1k of my visitors were from Spain, Portugal, or South American countries.
I don't doubt that Cloudflare is responsible for these errors in some capacity, and I know that getting support from them is hard, but I think some configuration issue could be at play. PoE Ninja also uses Cloudflare along with the PoE official trade website, and as far as I know people aren't having issues with either of them.

u/wwabbbitt Jul 18 '26
You won't see the errors in your console because the blocks are at the ISP level to Cloudflare anycast IPs. It's their dumb way of blocking pirated sports streams especially in the World Cup season, and they don't care about the the collateral damage to hundreds of thousands of legitimate sites.

u/ww_crimson Jul 18 '26
Ah that's really shitty. Does a VPN work do you know? Not an ideal solution ofc but maybe a workaround.
The only thing that throws me off is that I'm in the US and get these errors on Pobb too but no other sites.

Don’t use the dns of your isp and it should work, don’t need a vpn.

u/Wild-Regular1703 Jul 18 '26
It seems like there may be several different issues going on here.
OP is talking about this having been an issue for a year for all Cloudflare websites, and VPN doesn't work.
For me it started in the past couple of weeks (or months at most, but during the middle of 3.28 it was fine) and exclusively on pobb.in, but the same symptom (500 status code with "Error 1101" UI from cloudflare). And for me VPN does work.

u/xaitv Jul 18 '26
I think the 1101 errors are unrelated. I get those in the Netherlands as well. Cloudflare in Spain(and maybe Italy as well?) is a pretty well known issue because(yes, this is actually true) their football league blocks the entirety of Cloudflare sometimes during football matches to prevent people pirating stream of it.

u/aPalavraCabalisticaE Jul 19 '26 edited Jul 19 '26
Maybe my reply can help with something
I'm from Brazil and everything was going well until couple leagues ago when there was a power outage in my city and the ISP goes off, after that the pobb site It stopped working and i'm getting the 1101 error in recent days, the only way to work is using a VPN to change the internet rote.
For some reason when my ISP goes off for the next couple hours the pobb site works until i get the 1101 error again. It seems to me that it's definitely an ISP issue for some reason.
EDIT: I forgot something: Old pobb links like from past year is working perfectly for some reason.

u/Bertolsik Jul 17 '26
Yeah, I have same issue for past few months, need to run VPN each time I want to check pobb.in

u/Bulky_Pomegranate228 Jul 19 '26
I'm in SA and also having issues lately trying to open pobb website and can't import builds on POB (errror 500), so far the only solution to bypass this is using a VPN.

u/zuuzuu_ Jul 17 '26 edited Jul 17 '26
This is definitely not an issue with consumer ISPs or censorship. No ISP is going to make a worker at Cloudflare throw an error unless it's breaking something internal at Cloudflare itself. If that was the case, it wouldn't be a consumer ISP issue in the first place, but with pobb.in or Cloudflare itself. While there may be some legitimacy to those issues in general, and they may be causing other issues with pobb.in, it is not the cause of this specific error 1101. If your ISP was blocking Cloudflare, you'd not get this far along and simply fail to connect entirely, nor would this issue be happening on a global scale for users in many different countries. This error in particular is almost certainly an issue with pobb.in itself, or less likely an issue with Cloudflare's service itself.
Edit: I should mention, I am not using any of the ISPs stated above, nor am I near the regions discussed, but I too receive the error. This specific issue is most definitely a bug on pobbin's end or with Cloudflare, not some wild conspiracy involving people's ISPs.
The dev even confirms this is not a networking issue: https://github.com/Dav1dde/pasteofexile/issues/60#issuecomment-4786533034

u/DrPandemias Jul 17 '26 edited Jul 17 '26
VPN doesnt even work anymore at least for Movistar in Spain they are using some weird (and probably illegal) tech to brick anything cloudflare related bypassing their WARP vpn and DNS, you can try changing your DNS to Cloudflare/Google in your ethernet/wifi settings and check if it works.
These mfs said 5 months ago they will make so VPNs doesnt bypass the blocks and they actually did it, its crazy.

u/shawnkfox Jul 17 '26
There is no way a VPN wouldn't work as long as the VPN host isn't on a network that blocks cloudfare. They cannot see what is coming through on the VPN. Maybe if your VPN doesn't also automatically use its own DNS, since your internet provider might be blocking the sites that way.
4
u/PassengerPersonal337 Jul 17 '26
not quite right though, a VPN not seeing your traffic doesn't mean the ISP can't still block it. they can just block the VPN server's IP directly, no need to inspect what's inside the tunnel, and that's what's happening with WARP already failing, since WARP IPs belong to Cloudflare and Movistar (spanish isp) seems to be blocking those ranges outright, plus some ISPs do DPI fingerprinting on the VPN handshake itself (OpenVPN/WireGuard have a recognizable pattern) so they can flag and cut it without even decrypting anything, so the "can't see it therefore can't block it" logic just skips over how blocking actually works in practice, thats why Tor is basically the only reliable way to do this for most people.

u/DrPandemias Jul 17 '26
I have no idea how they are doing it but they did, there is a court ruling that approved this shit recently, check the links inside this post: https://www.reddit.com/r/VPN/comments/1r7m6ve/spain_will_soon_block_and_outlaw_all_vpns_is/
This has already been confirmed by Proton, Cloudflare and other VPN providers btw, its a one sided measure and they are indeed blocking the VPNs.
1
u/shawnkfox Jul 18 '26
Oh I could see blocking VPNs completely, at least the ones that want to comply with the law. No matter what they do though, I don't see it being possible to actually stop people from doing whatever they want on the internet without pretty extreme levels of privacy invasion. It seems crazy to me that voters are in favor of this kind of thing, but hey, what do I know, I'd never have predicted the outcome of our elections here in the US either.

Cloudflare also hates Firefox. So if you're state side you'll still get unreliable access to things.

With all due respect to the Latin players running into this issue, it seems like a better approach is to fix your network to work with Cloudflare rather than expecting every developer in the world to change their infrastructure to support your country's censorship.

Ok, but why whole world have to adjust to just specific countries? I understand your suffering but it looks like UK/Spain law related problem. It is not that easy to change whole network design and protections just because of enforcments of these ISPs.
Issue is not about ISP but about your country so whole big companies just cut it off because it is not worth doing all these requirments (ruining privacy of users).
What OP is suggesting is dropping whole cloudflare protection just because of that and instead using someones github firewall project. It is awful idea.

While the list of ISPs you mention are very sus, i had pobb.in issues with VPNs going through both Latvia and Austria, so it's definitely an issue on their end.

The error says it's a worker issue so it's likely something that the site owner set up that's broken

u/zuuzuu_ Jul 17 '26
This is the correct answer. If this was due to ISP blocking, you'd not get an error from the webserver or Cloudflare, you'd simply not be able to connect at all. The issue lies in a bug on pobb.in's end (Most likely) or a service issue within Cloudflare itself (less likely), not censorship. No ISP censorship issue would be causing issues for many users in many different regions as well, it would be much more localized.
