Same error while upgrading the main vSphere Replication appliance itself.
seems like some confusion on the source and target regarding IPV6 even though i am using IPv4
I have highlighted where i think the "check" is failing. if anyone has experience of this i am all ears

It appears these warnings are cosmetic and if the rest of the config matches up you can select Ignore after it eventually fails on the check
everything else in the upgrade seemed to work!
always nervous about these vsphere rep upgrades as ive had some really bad experiences over the year
