Muster Render Client Service 9 windows error

Version 9.0.14 build 11632

We’re experiencing some problems with the Windows Muster Render Client Service 9 . When a computer is rebooted, node status doesn’t go from grey to green status. In the \Muster 9\logs\client\activity\renderclient.txt file I see the following error:

Logging in and restarting the Muster Render Client Service 9 service works:

I tried setting the Muster Render Client Service 9 service to delayed start(2min delay)in Windows. That actually had it working again 100% at every reboot.

My first thought was that the Muster Render Client Service 9 service starts before a specific Windows system service and thus the error. I’m looking into setting up some service dependencies and triggers. But I uncertain what actual Windows services Muster Render Client Service 9 depends on.

Or it could be Muster server.

Has anyone in this forum experienced anything similar? Any fix suggestions other than just keeping a delay on the service. 2 minutes in renderworld is a lot.
