hello guys i have a problem i had 4 servers i had made it before 1 month and they work perfect but today when the 4d1 close and open again later when i go to my server it say to me attemp session 1.2.3.4......

and my server isnt in server list why???

i make a new server but again the same error pffff

Probably your ports are closed somehow, my opinion.

 

Check the forwarded ports if 'UDP - 28960, (or whatever port you put in the shortcut of your server)' is opened.

Same error, but unless he got a new router or update or something his ports wont suddenly close?

 

I know I didnt suddenly close my ports..... and I have the same problem.....

i have open my ports sucesful but i have the error yet
