Upgrading VirtualCenter to 6.7.xx you get: Error in method invocation Timeout happens while sending message to microservice #vsphere #vcenter @vmware

I did get this on 2 different upgrade I did I tried two methods both worked for me.

Reboot VirtualCenter server and do the upgrade again

Or

ssh into the VirtualCenter box and type:

rm /var/run/vmware/applmgmt/update_microservice.pid

Upgrade again!
