Having the same issue here too with the build 6285. Raised yesterday night on this and seems there is several other users also facing this same issue.
Manu Tabtim:
To investigate further, I downgraded MT5 to Build 6230, and everything started working normally again.

good test, that pretty much confirms it. the same error is being reported in several threads since yesterday, all of them on 6285, and Renat Fatkhullin already posted that they are looking into it. so its not the accounts or the passwords, no need to keep resetting them.
trading and EAs keep working normally, only the community login fails. for anyone landing here, staying on 6230 until the fixed build comes out is the cleanest workaround.

Hello,
Today, I installed MetaTrader 5 and received Build 6285. Immediately after installation, I encountered the following error:
MQL5.community: authorization failed
This error appeared even though I had not attempted to log in to the MQL5.community account.
I then tried logging in to my MQL5.community account, but the same "authorization failed" error persisted, despite using the correct login credentials.
To investigate further, I downgraded MT5 to Build 6230, and everything started working normally again.
This suggests that the issue may be specific to Build 6285.
I hope this information will be helpful in identifying and resolving the issue in a future build.
Thank you for your attention
Best regards,
