Hello OptoIT,
The comparable configuration file on vCSA is:
/etc/vmware/service-state/sps/sps.properties
I have made a personal note to contact the kb author for adding the necessary details for vCSA to this article.
Are you sure this timeout/re-connect is the issue?
What is the exact message you are seeing in vSphere Web Client?
What does the sps.log report when this is occurring?:
Default location is /storage/log/vmware/vmware-sps/sps.log
