Gmod Authentication Error?

Today, I was joining a server and there was a white screen that had the gmod symbol and it had an “Authenticating with Steam” and I let it sit for 30 minutes and it still wouldn’t let me join… HELP!

I reinstalled the game and verified the integrity of the game cache AND THEN I GOT 1 FILE detected and stuff then I still have the authenticating with steam…

This all happened after i deleted my cilentbloobly thingy…
