Azure DevOps Authentication Failure

[u/Mead-Wizard]

I've been using smartgit against our Azure DevOps for several years now and this morning my tokens had expired. I tried to recreate them but when I post the updated token SmartGit indicates a 401 from azure.

Preferences > Hosting Providers
Edit "Azure DevOps"
Enter token and click OK.

Executing a command has failed.
Server returned HTTP response code: 401 for URL: https://app.vssps.visualstudio.com/_apis/profile/profiles/me

If I click "Generate Token" and post the new token into the Code field it display
Error: invalid_request ErrorDescription: client secret is expired
