i joined the game jam and tried to join the discord, but it says that its expired or i don't have permission, is it because the jam will start soon 4 hours later, or something else?

The discord link works for me, and is valid. Possibly you've been banned from the server? When you're banned it can just say expired.

Hello,

We have verified the link and it seems to work for us. I went on the server and pulled a fresh invite link, give this ago https://discord.gg/WbpRVSnh

Thanks,

sorry about the trouble earlier, my discord was acting up— long story short it kept trying to log in with a deleted account because my internet drivers weren’t updated properly. I’ve fixed it now. thanks for sending me the link again, thanks a ton! :D
