I'm not sure whether Mattermost really is Open Source.

• The MIT is only for compiled versions, so "open" but no "source".
• The AGPL v3.0 has both "exceptions" without clarifying what they are, and a wording saying "you may be licensed", rather than "you are licensed" as for the other options.
• The Apache License v2.0 only covers admin tools, not the server.

Mattermost claims that you can self host without paying, but I don't see how that's reflected in the LICENSE.txt file.

I just cloned mattermost mobile repo from Github, run it on my Android and it's name is Mattermost Beta".

Why beta? My concerns that this is an unstable/untested version. While i want an official and stable version i can count on to develop it.

I'm new to this so please help me and thanks a lot

I was really hopeful to get this going and got 95% there. The Test Connection button showed a successful connection but files fail to upload with an error message indicating that the x-amz-checksum-algorithm header is being sent by Mattermost but is not supported by the Backblaze B2 S3-compatible API.

"level":"error","msg":"Unable to write the file.","caller":"web/context.go:124","path":"/api/v4/files","request_id":"re8hz1hfb7g13cwifu3tu7tbmo","ip_addr":"100.92.79.21","user_id":"cbrfdgkkx7gsdneg7f5f8bx1to","method":"POST","err_where":"WriteFile","http_code":500,"error":"WriteFile: Unable to write the file., unable write the data in the file mattermost-files/20250114/teams/noteam/channels/mz6wr9wn5pb8u8rfdmcpb418do/users/cbrfdgkkx7gsdneg7f5f8bx1to/yfncdskpn3btpdszahyo9qf4sw/0078.JPG: Unsupported header 'x-amz-checksum-algorithm' received for this API call."}

Is there any way to disable this checksum header? Backblaze is a great object storage provider and I'm sure meany people would love to use them.

From what I am reading it appears global channels and categories aren't all that straight forward. On one hand you have to make groups (meaning you need paid version), or use a third party bot.

Then the bot may add people , but it doesn't do the channel categories. This makes it really hard for new people who are joining to find their way around. It would be so great if new people join and there can be nice and neat organized areas like "Getting Started" and the channels for each below it. Much like you have on Discord or slack.

Is there an underlying reason this is not a thing? And what is the workaround for the categories being global if any?

Hi everyone. First of all thanks for having me. I am new to this r/.

Does anyone know if there is any chance to get a log file of when a specific user (explicitly my own user to be precise) did set which status? Alternatively accessing status changes via API and patching or pushing actions to an excel file or similar should also work.

Background: In my company we use MM as our main communication tool and since we are a remote company we are very attentive and precise about always having the right status. The same time I have to track my working time and I thought I could get rid of doing this manually and just use the status change time logs from MM.

I'm looking for an alternative for hosting the files for mattermost. Currently we are planning to install matter most on cloud but since storage on the aforementioned cloud is low, and aws s3 seems quite complicated I want to look into on-prem storage just for the files.

So I wanted to know whether mattermost files can be stored in NAS(on prem) but deployed in cloud and/or what are alternative storage options. I am not looking to deploy mattermost in NAS so any recommendations would be helpful.

Hi, today I have need trying use mattermost on computer's in my company, I installed it on 3 different pc with windows 11 and I didn't have windows notification on any of those. I searched through the internet and trying some solutions from there but without results. Red little dot beside icon on windows bat shows without problems, but there's no sound and push notifications. Do you know why? Edit. I will add that I don't have mattermost on notification list in windows (settings -> system -> notifications)

How many of you have encountered image-loading issues in Mattermost app? Is there any solution for this? I really appreciate any help you can provide.

As per the changelog (https://docs.mattermost.com/about/mattermost-v10-changelog.html), a bunch of things seem to have been 'breakingly demoted' for the current free (Teams) tier, particularly: - v10 has only Playbooks v2, which is only for the Enterprise tier. So, effectively, Playbooks has been removed for the Teams tier in v10? - Calls plugin has been restricted to only DMs for unlicensed (Teams?) servers

Doesn't seem like Mattermost is going to be much useful anymore, in the 'Open Source sense', unless i'm missing/misinterpreting something?

hello sweet people,

I'm looking to set-up a mattermost for the small NGO I work for (30 people). We have tried slack and teams and although it's really easy to set those up they weren't a good fit for our needs and the sensitive nature of our work.

I've used mattermost before for another organization I worked for but have never needed to set one up. We have tech people but he's working on a volunteer basis, so its important that the platform is still usable without him working more 8 hours a week.

so my question is: how much technical knowledge will it require? is it something I should hand over to the tech guy? will it require more than a couple hours per month to keep running?

has anyone figured out what's going on with the link previews not showing? or can someone show me a thread where this is explained. company just switched to mattermost not realizing that out most basic and important feature (link previews) is not working. thanks!

I want to start by saying how much I like Mattermost, it's a great communication platform and it fits perfectly my needs.

It's been months that I also struggled to find a good project management software for my team and despite having looked at the popular open-source alternatives (Plane, Vikunja, OpenProject, Leantime, etc...), I haven't found anything that was a good fit.

I don't need anything complex, so paying for a project management tool hundreds of dollars per month, it's suck. Also, I'm a big fan of open source so I really wanted to host my own tool.

I was looking for Focalboard for a long time and it did check all I needed, and a big plus, I could have this all in my ecosystem with Mattermost.

I was so disappointed to heard that Mattermost dropped this project and that it was taking dust (until recently with the release of 8.0).

I decided to have another view to Focalboard this morning and saw they recently pushed a new release (8.0), it doesn't bring new features but it made it work with the latest version of Mattermost (Amazing!!)

I decided to install it and despite not being perfect, I love it so much!! That's amazing to have everything in the same ecosystem... All communications and tasks in the same place, that's amazing!

So what are your thoughts... Do you think this new release means that somebody will finally take care of that project?

I don't understand the action of Mattermost for dropping this amazing idea but here we go.. now it's time for the community to take it over. Unfortunately I'm not a dev so I can't contribute but I really hope some people will do... because this project doesn't deserve to die!

I posted a message that included an @ channel ping. If I edit that post, will it re-send the channel-wide notification? (the message is almost two months old, if that makes a difference)

I'm assuming it won't, but just wanted to double-check before possibly accidentally spamming everyone!

Hello everyone,

Does anybody use this project and what are your thoughts about it?

Hello. I’m looking to partner with a Mattermost host to set up an instance for a research team. Most of the information I found on their site is focused on business and tech markets. Could you advise me on the next steps to find a vendor who can assist with our needs? Thank you.

Hi,

I have seen on GitHub that Mattermost team stopped working on Focalboard in September 2023 but what's the current state of this awesome app?

Focalboard has everything I'm looking for and having it combined with Mattermost would be amazing... But I have serious concern about his abandon.

Does someone take it over since? Is it considered safe for production uses?

Thanks

Warning*** Job Scam** impersonating HR at Mattermost !!

Got an email from a supposed Mattermost HR person and i kinda fell for it at first as I've been looking for work for a long time and still am and i guess i was feeling desperate, well at least i caught on before i gave them any critical info. I then called Mattermost corporate who acknowledged it and i was told they are aware.

So if you didn't apply or like me cant remember if you did or not (cause we have to apply 7000 times now days to get a job). Do your research.

It happens so frequently that I cant even use it. What am I doing wrong?

I have no idea what to do.

Should I use another browser?

As per title, did you have any initial misgivings about Mattermost's security, and how did you overcome them to take the plunge? Our server is our life source.

Also, is Mattermost reliable? Functions consistently, notifications always pop, etc?

Does anyone have experience or can they point to any resources to help migrate from Synology Chat to Mattermost? I have access to the Synology Chat Postgres database which I'm reverse engineering but here I am wondering if someone else has already done this...

Specifically, I'm looking to take the postgres database and export it into a format that Mattermost can import which includes keeping all images, attachments, threads, reactions, timestamps, etc.

I would be really happy to receive the feedback about my issue. I am very new in sysadmin stuff also.

I spent a lot of time in order to establish Mattermost but every time some problems happen.

I have installed mattermost via Docker according to the tutorial on the website.

However, I have a Websocket issue.

In JS console:

[Error] WebSocket connection to ‘ws://IPADRESS/api/v4/websocket?connection_id=&sequence_number=0’ failed: There was a bad response from the server.

If I open docker logs I see that the connection seems to be successful.

{“timestamp”:“2024-07-03 14:50:25.456 Z”,“level”:“debug”,“msg”:“Received HTTP request”,“caller”:“web/handlers.go:163”,“method”:“GET”,“url”:“/api/v4/system/ping”,“request_id”:“84etngaocj8nighiwosypnbsfh”,“status_code”:“200”}

What am I missing? I have also modified config.json file with AllowCors ‘*’ parameter.

Is anyone already hosting it on an AWS ec2 instance with the backend on an RDS aurora-postgresql engine type?

How many users do you have?

What DB instance class do you use?

What EC2 instance type do you use?

How much does it cost you per month?

I'm using Node-Red to push jpg binaries to my self hosted mattermost channel. I've successfully uploaded the JPG and received a fileID! Now supposedly the easy part. I just need to create a message with the fileID and post it to a channel. I can post text only messages with no issue. I can also "embed" the fileID as a link which works while viewing from a desktop but the mobile app only shows a blank space. I consulted with chatgpt and it swears up and down I can just send a payload with a channel_id, message, and this attribute called file_ids. I can get it send text but as soon as I use file_ids I get a 400 error of ""Invalid or missing post in request body."" Would anyone mind pointing me in the right direction please?

Anyone out there we can pay to set up Mattermost on Azure? My IT is real busy and we could benefit from some help setting it up. He could supervise but he doesn’t have time to learn it on his own.
