oh weird. i had something similar happen last month, tho not error 0. did you try restarting your router? sometimes that fixes random connection stuff. also maybe check roblox's status page, could be their servers are just having issues rn. tbh, sounds like a connection thing or something on their end.

another thing to try - go to AppData\Local\Roblox\Logs and clear that folder, sometimes corrupt log files trip the auth flow. also if you're on windows 11 make sure roblox isn't being blocked by the new app sandbox stuff. if router restart didn't help, try logging in via browser first at roblox.com - if that works it's a client install issue and a clean reinstall usually fixes it.

Roblox Error 0 (Authentication Failed) typically means your device is struggling to securely connect with Roblox's servers. This is often caused by corrupted local cache files, a malfunctioning VPN, or temporary server outages. Turn off the vpn and check if there's a server issue.

Code 0 error in Roblox typically indicates authentication failure owing to server problems, incorrect credentials, and networking issues. Restarting, troubleshooting the Internet connection, clearing cache files, and resetting the password might help.

Error code 0 on Roblox is usually a connection or client issue. I’d first try restarting your PC and router, then launch Roblox as admin. If that doesn’t help, clear the Roblox cache or fully reinstall the client because corrupted files can cause that gray box. Also, check if Roblox servers are having issues today, since sometimes it’s on their end. I’ve seen random login problems fix themselves after a while when servers were acting up.

Roblox Error Code 0 means authentication failed due to server issues, expired login, VPN, cache, internet, or wrong device time. Fix by relogging, clearing cache, updating, or disabling VPN.
