STEAM AUTHENTICATION FAILED: TICKET INVALID (after queueing into full server - official and community)
Assigned, NormalPublic


So we found out that a lot of times just when at pos 1 and about to join in we get above error message, which drops you back at the server browser.
You need several tries, to finally be able to join a full server.

What we also realised (i say we as we are a group of 5 people), that often a few of us at the same time end up in queue position 1. Which obviously should not be.


Operating System
Windows 10 x64
Operating System Version
win10 pro, newest version
Steps To Reproduce

Try to join for example: TheRunningmanZ server by Spaggie when it is full.
Wait until you are at pos 1 and hope to join the server -> In most of the cases, you will get above error message and drop back out agian.

8/10 tries, we fail to join in.

Was seeing this repeatedly on ExecCS's stream last night as well. This only happened after waiting in a long queue, so we speculated that by the time the queue system tries to join the server, perhaps the auth ticket had timed out. Maybe the queue system needs to take steps to refresh or keep alive the auth ticket?

Hello mofokrazi.
Do you remember which specific day/hour was it occurring on the TheRunningmanZ server?
@Spaggie Would it be possible to get the server RPT files from the server so we could take a look?

I will add files to the Private ticket at: to protect our Users

There's also some more information there


@Geez it happens almost always when the server is full and a queue bigger than 7-10.
For me and my mates, last time we tried was yesterday 18.12 at around 17:00 to 19:00 CET.

Also happened on official servers.
Two days ago at DE 0-2 around same time if i remember.

Only when full and long queue. But then almost always, for several people across Europe.

@Geez just for info, right now it happend again on TRMZ server by @Spaggie - was queueing in starting at pos 20. Went down within around 30minutes to 1, then had the STEAM AUTH FAIL again.
It is basically almost impossible to join our favorite server.

Just for info, right now it happend again, was queueing in from 18, down to 1 at TherunningmanZ server, aaand Steam error. (Same for a friend)

I will send today's RPT on that other ticket

Hello everyone.
Was your game minimised when connecting and receiving this error by any chance?


Nope, no alt-tabbing, no minimizing. nothing like this.
Just after a long queue. Really, try it out yoruself guys, there is a 70-80% chance you will have the same on a full server with a queue above 8-10.
