Uh I am sorry if my question is stupid but I really could not find any solution to fix this problem.
It has been days already since I can't login CIT. I don't play other servers so I dunno if it is MTA related or just server. I tried to login others as well. Same situation.
Thing is - whenever I double click on CIT's IP through MTA (as default u know) I get an error called CC23. That is related with connection, I know that. But I've tried many ways to fix that but unfortunately nothing helped. This is why I opened this topic.
I've updated MTA (it was outdated).
I've allowed "gta.sa" in firewall (it is recommended on board).
I've restarted computer and Wi-Fi modem many times.
I've turned off VPN and proxy settings (I use them due to internet problems in my country, nothing related to games).
What else can be wrong?
I could not fix this problem. Even with VPN. But now everything is fine. I was not able to login because of temporary internet limits in my country. Limit is gone and connection is possible rn.
Thanks for your time!
