Connecting Issue

[Iczenumi]

Hello there, there is new problem with content manager and assetto corsa in these days. Some people on my discord channel (We are in like 7K People at there) says "Connection Issue" problem when they connect my servers and loading finished. I check the LOG from my servers it seems no problem at there. I was dont have any problem like 7-8 months but now im facing with same issue with ALL servers from anothers and mine. When i trying to search servers from Assetto Corsa server pings are not checking. It seems with RED BACKGROUND n/a ping. I tried with content manager it show all server pings "?"

I tried;
Forwarding Ports
Disable Firewall
Unistall AntiVirus
DMZ
Hard Reset Modem
Adding Exception from firewall to AC.EXE and ASSETTOCORSA.EXE

But there is weird problem when i try to connect with VPN, i can connect all servers and my server. If i open VPN all server pings are checking and working. My Connection Issue is fixing. But if i close VPN all things are gone and im facing with "Connection Issue" in game.

I attach the screen for "?" pings.

I found the solution, i researched the problem is "Dynamic IP", so if ur IP is in CGNAT pool then u cant use port features and more. So this means our IP was on CGNAT.

How we can know "we are at CGNAT?"
Answer Is: Go to your router screen 192.168.1.1 or whatever is it. Go to WAN then check your ppoe_ ip adress. If it is starting with 10.xxx.xxx/32 or something like that, it means u are on CGNAT pool wich not supported for Assetto Corsa.

Now im using Static IP and my problem is solved.
