[ROBLOXCRITICAL] Cannot join games: "Security Key Mismatch"

Myself and many of my friends just noticed that we can no longer join any games.

Happens every time on all games.


A ton of people from my community including myself also getting this across multiple games.

Thanks for the report. Our engineering team is looking into it.


Same here

Site is also running slow, yet roblox.status.io isn’t showing anything.


Same here, and a bunch of other people in my group are having the same issue. They just suddenly weren’t able to join my VIP server, even while I was in game.

I was in the middle of testing some anti-exploits and lag while reseting, so I thought it was on my end. Really happy that it was Roblox’s fault, not mine :stuck_out_tongue:

Same here its everyone.

I got it as well! It’s weird as I just played a game 15 mins ago.

Yeah, as far as I know everyone I’ve asked is having this issue.
I assumed it was on my side at first, as to my surprise reinstalling the client did not work.

Some people from a Discord server I’m in noticed that the game doesn’t give you that error for the Robux scam game on the front page.

Maybe that has something to do with it?

It seems to have been fixed (at least partially). I can play games now with no issues.
