Dedicated server acting up.

Today I updated and started up my server. I went to join it and I got the “Connection failed after 4 retries” But other people can get in. Also when I had srcd’s running I couldn’t join other servers.
When I am not running my server I can join other servers fine. I tried restarting my computer, restarting my modem and router, restarting steam, etc… etc…

I’m very confused as to why its not working. I haven’t changed anything since last time I have played on it. Except for updating.
My server was running completely normal before today. Could someone give me advice on a fix? Thanks.

connect from your local ip not internet ip
