did you log in into your classicube profile? otherwise this might be because the server is in online mode and you need a valid Minecraft session, either way I can't reproduce this.

[Saraistupid]

Yes, I logged into my ClassiCube profile, I said so in the steps, I have a question tho, how would a ClassiCube server using online mode cause any difference?

[FlorianMichael]

I think ClassiCube servers can still require a valid Mojang/Microsoft account session

[Saraistupid]

ClassiCube doesn't check for a Minecraft account session afaik, but if that's the case, I'm using a valid Minecraft session, I can join non-ClassiCube servers just fine, even c0.30 ones on BetaCraft (with online mode enabled)

[FlorianMichael]

How many servers did you test? Can you provide the names of some you tried so I can test them as well?

[Saraistupid]

I tried these first few servers I saw on the list (seen in the screenshot), as for the BetaCraft servers I tested, I tried ClassicHaven, OmniArchive Classic, and The Grand Province (not online mode), which all worked just fine

[FlorianMichael]

I can't reproduce this issue with the same servers, maybe try to create a new ClassiCube account / try logout and log in again.

[Saraistupid]

Sorry, I forgot I opened this issue, terrible memory issues
I tried logging out and logging in, weirdly enough a new ClassiCube account works, my original account still doesn't work (I just tested in ClassiCube and I can join servers with my original account as expected, but not in VFP)

[FlorianMichael]

Hm no idea honestly, can you send the client log when logging into the "broken" account and joining a server?

I can provide the account's login details privately if needed
