failed to connect to host server

Failed to connect to host server error- I thought this was a problem on CF side but it seems other posts say it's users side problem. I tried putting CF in firewall and tried disabling firewall completely as suggested by other posts but the error still happens after about 10 minutes into game. Happens on US and UK servers. I'm in the US and have about 50-55 ping on US servers. Is it my router? I'm on Windows 10... any ideas on what I need to do to stop this error?
