"Steam Validation Rejected"

I’ve tried Googling for the answer to this question, to no avail. Now before you call me out:

I DO OWN GARRY’S MOD.
I AM NOT TRYING TO CREATE A SERVER, I’m trying to join a couple of friends in the server they are in.

I’m simply able to get all the way to “Sending client info”, and once I’m about to enter, I get the “Steam Validation Rejected” pop-up.

Help?!

DO YOU OWN GARRY’s MOD?

ARE YOU TRYING TO MAKE A SERVER?

Witty.

I was testing you to see if you were one of those players who would say “FUCING TROLL I H8 FACEPUNCH I GON GET GARRY TO BAN U FROM HIS GAEM!?”

Honestly forgot the fix, almost everything can be fixed with verifying cache, does anyone else get this problem? Since its Steam validation you should just have to verify your game cache, happened to me before.

I think I figured out the fix. You’ve got to change “RegistryClient.blob” to “RegistryClientOld.blob” and restart Steam.

Also, nice test.

You have to be an alt, just sayin’
