Turns out the Photon OS on the SRM 8.2 appliance does not like spaces in the passwords. After figuring out that the postgres DB was not starting, I was able to reset the root password so I could look at the logs. Reinstalled with passwords that did not include spaces. All is good.
I had the same error just now. In my case, my original DNS servers were retired and needed updated. All worked correctly after updating the DNS to functional servers.
