Client not authenticated! 403: Forbidden

Hello,

Running latest 1.20.1 with

fabric-api-0.83.1+1.20.1.jar lithium-fabric-mc1.20.1-0.11.2.jar NoFog-1.3.4+1.16.5-1.20.1.jar sodium-fabric-mc1.20-0.4.10+build.27.jar

When connecting trough world-downloader the server says I'm not authenticated, when connecting directly to the server within the same session it works fine.

Tried it without the mods and world-downloader works fine.

So seems to be an issue with the mods and world-downloader not working together.

Upgraded to latest mods including fabric loader 0.14.21 -> 0.14.22 wich I forgot to list above.

fabric-api-0.87.0+1.20.1.jar sodium-fabric-mc1.20.1-0.5.2.jar

Still the same issue.

Automatic authentication doesn't always work, you'll have to use microsoft authentication or provide an auth token.

Thanks for the info. Figured it out, never tried the GUI before, only ever started it in cmdline and didn't see the options for it there or in docs.
