Thanks for the quick reply.
The nodes.properties has the machines listed, matching what the admin API shows.
Portal1's postgresql.auto.conf file has Portal2 listed for primary_conninfo, while Portal2 as Portal1 listed in the same place.
Both config-storeconnection.json files have each machine listed, however, Portal2's string has "/gwdb?targetServerType=master" as the end.
The arcgis#sharing.xml file on both servers has "jdbc:postgresql://localhost:7654/gwdb" set as the url property.
Would updating these files manually fix the issue, or is there a better way? I know that any unexpected formatting, or incorrect syntax can break things quickly and would prefer to not restore the VMs.
