"Failed to Authenticate Using OAuth (1)" 12002: The Operation Timed Out

Hello, I have the same problem.

Situation
In December I could use MP3tag (v3.28) searching Discogs. Now it fails with the (partly Dutch) error message:

Failed to authenticate using OAuth (1).
>12002: 12002: Er heeft een time-out van de bewerking plaatsgevonden.

Note, "Er heeft een time-out van de bewerking plaatsgevonden." is Dutch for: "The operation timed out."

What I tried so far

  • Remove the "mp3tag.cfg" from "%AppData%\Mp3tag". I even removed the whole directory without results.
  • I ran CCleaner (free edition) to clean my system and Spybot Search & Destroy (free edition) too. I removed the Immunization applied by Spybot, assuming it could be a problem like "using a firewall". But it was not...
  • I revoked all the MP3tag authorizations in my account at Discogs -> Settings -> Applications. Not triggering a new authorization request, so I think there is no connection established for some reason. Therefore, I suspect the time-out occurs before connecting tot Discogs.com.
  • Increased the timeout in MP3tag from 10 (the default) to 120 seconds.
  • I only have this error when connecting to Discogs. Connecting to freedb and MusicBrainz is not a problem.

Question
Does anybody have a solution how to fix this?
Thanks in advance!

My system and software versions

  • MP3tag version 3.28 (Dutch language).
  • Windows 11 Pro version 24H2, build 26100.2605 (Dutch language). Including the latest updates.
