Hi,
With Valve's help, we have an update out for the ZPS server community. This will fix the "STEAM certificate length error! 0/2048" issue that appeared this week. The issue was related to the Linux Dedicated Servers and one of the most recent Steam Client updates.
Server owners (Linux ones in particular), if you haven't already you need to make sure that your server is properly configured to use SteamCMD.
Once you've done that, you need to update your ZPS server files with SteamCMD. Our Server AppID is 17505.
