The other day, my scheduled publish tasks all failed and a scheduled metadata reload didn't finish. These tasks have all been running perfectly for months, every day. I am running NPrinting May 2022 SR4 and Qlik Sense Enterprise Feb 2023 patch 1. I see this error in the Scheduler log about 3 hours before the failures:

A couple hours after that, an import task runs successfully, and then 45 minutes later, this error appears about 60 times:
Qlik.NPrinting.Scheduler 22.15.14.0 Qlik.NPrinting.Scheduler.Service.LoadBalancer 20230810T054549.664-04:00 WARN EWHSERVER2690 0 0 0 0 0 0 0 0 Connection navigator=qliksense;proxyurl=https://***servername***/;appid=3a9a0d38-cb35-4b5b-b590-e9f6bb11ca7a;identity=ewhserver2690\nprintadmin recorded an error in startup
And then this one:
Qlik.NPrinting.Scheduler 22.15.14.0 Qlik.NPrinting.Scheduler.Service.ConnectionStatusMonitor 20230810T054553.541-04:00 ERROR EWHSERVER2690 0 0 0 0 0 0 0 0 ConnectionStatusMonitor: Maximum number of errors reached and all allocations are on error for connection navigator=qliksense;proxyurl=https://***servername***/;appid=3a9a0d38-cb35-4b5b-b590-e9f6bb11ca7a;identity=ewhserver2690\nprintadmin. Setting connection status to error.
Any ideas what would cause the initial error? Thanks for your help.
