Can't connect to certain servers

[BigGunZ]

For example:

i can connect to hlin 6999 but not 7999. Response is "cannot connect to server" basically a timeout. This started happening randomly a few days ago. I also can't connect to Godsmack, and im sure there are more. Seems to depend on the port?

Need some help here.

i have issues like this with lolol and la dyhclan servers

i connect to them but CAN never actually play (1000+ ping) and its just shit. I restart my router and it sometimes helps

it happens to me sometimes too. I just restart AC and it works after that. no idea why lol

I have it too sometimes. I just connect to another server first. After a minute or something I connect to the server I wanted to go to. If it doesnt work I do the same as Edward.
