Unable to Join 2 instances of Portal for ArcGIS

[MwalimuKaranja]

We are currently doing a high availability installation of ArcGIS Enterprise and keep running into a few installation issues with the joining of the portals. We are using an ArcGIS Enterprise Advanced License to license both portals but keep getting the following error:

The two machines are licensed differently. Ensure both machines use the same level of licensing

The only problem here is that we are using the EXACT same license on both machines which used the exact same setup. Could anyone offer some suggestions on why this might be happening as well as assist in helping chart  a solution for the same?

Any update on this? Setting up 10.6.1 and portal for the first time and ran into this issue.

If the licenses are identical from the keycodes file, then it's likely the time zones of the machines are different. Make sure that the time zone on each Portal machine is identical.

The time zones on my machnes are different as they are located in different time zones. Seems like a bug if that actually matters. However, I did try changing the time zones to match with no luck. ESRI support tried to help and we could not solve the issue. Had to due redundant server on same site which is not what we wanted but have no choice.

[JonathanQuinn]

I would agree that it's something we need to address in the software, but I would advise against joining two machines that are not in the same data center or geographic area. There is a significant amount of chatter between the portals to keep components in sync and any latency or distance between the machines is going to be a problem. If you're interested in geographic redundancy, set up a separate environment in the other data center and use the WebGIS DR Tool to replicate data and content to the standby site.

both machines on UTC?  (it is a good habit regardless).  

[BrianLeroux]

No, we do not configure our server to UTC. That is an architecture decision beyond my control.
