Windows 11, it shouldn't be that because i was using forge just fine until 1.18, when i tried to install 1.18.1 forge it f'd up everything including the older version i installed

[Bernardosm]

Fixed, even tho i clearly disabled the anti-virus it was still working and the issue was that it was blocking encrypted connections (Probably activated by a anti-virus update)

Kapersky -> Settings -> Network settings -> Encrypted Connections scanning -> Select: Scan encrypted connections upon request... (or do not scan connections, could work)
