What to do when games do not connect to the server on Windows 11 (for LoL tft and Steam)?

Hi. I have Windows 11 installed about 3 weeks ago. Steam games are downloading. I log in to my steam account, but the games themselves don't log into their servers and I can't play. The methods on the net don't work. The thing is, it doesn't connect. Has anyone had similar? There is permission on the Windows Firewall, e.g. for League of Legends, but it still does not connect after entering the login and pass in the game. It opens the game and inside it does not connect to the account. There is a timeout :"There was an unexpected error with the login session. Please try again."
I messed around with the Firewall on the modem, but I don't know how to set up redirection there. Network monitor on computer shows Outbound port riot and lola are 443 and local ports are different 53623, 53642 etc. Help! How do I unblock this connection and let these games pass? Whoever solves the problem gets paid haha.
