MP - MULTIPLE PLAYER DISCONNECTS (ONVALIDATEAUTHTICKETRESPONSE RESPONSE=6)

[ZipperNeck]

Hey PZ forum, we had 6-10 players on our Zomboid server (Havoc hosted) and throughout the day (~20 times) players were getting 'randomly' disconnected. Everytime we see this in our logs....

If it happens players can ultimately rejoin but seems to have no relationship with mods or server load.  After 'my own research' it appears to be PZ source code calling steam API, specifically authenticating players steam session ticket....

Can a developer or other expert tell us what response=6 means?  From my perspective it feels like our server is validating player session tickets (who have already authenticated and connected) every X minutes.  Sometimes (steam API is overloaded?) this validate call is timing out - either due to steam API load or client read/connection timeout values being too low.

Thanks in advance!

Response 6 means Steam canceled the auth ticket.

 

I assume it means they lost connection to Steam itself and it timed out.

 

 If it happens on Tues/Wednes, it’ll likely be because Tuesday is the day Steam does maintenance and releases client updates.
