Server won't connetc through external IP all of a sudden

A friend and I play on my Gmod server pretty often and in fact played last night. For some reason now my server isn’t connecting through my external IP. I have everything forwarded right and my local IP hasn’t changed. I tried restarting the server, my router/modem, and my pc but nothing is working. I really have no idea what could be causing this. Does anyone have a suggestion?

Local IP didn’t, how about public?
