Cannot Connect to Friends Server

Hello, Im trying to connect to my friends server through the server list and dc, and its giving the same error code for both. 10060, Is there anyone who can help. He can connect perfectly fine but I cannot.

10060 is a port forwarding error.
make sure your friends server is port forwarded correctly

im having the same issue and attempted to port forward and still didnt work

Try a port checker and see if your port is open. make sure the server is running first, then use a port checker.

if my friends server is port forwarded, how do I input the information correctly for my modem to port-forward

The server host needs to port forward. If you are joining his server and are getting error 10060 then HIS server is not port forwarded correctly
