RP4VM - The cluster is unreachable

Hello,

I'm running into a strange problem that has occurred at two sites with RP4VM (entirely separate environments with no relation to each other). Shortly after the installation completes the vCenter listed under Administration -> vCenter Servers displays "The cluster is unreachable. Probably due to VC credential change. Please update". To clarify, it seems to work for a while where it will display the vCenter and show connection as ok but then degrades to this state.

In both cases: The vCenter service credentials have not changed and neither have the user accounts on the Recoverpoint. If I try using the edit link to input the information again, I get the following error: "Authentication to RecoverPoint failed, Have you changed VC credentials lately?".

I can login to the RP clusters using both admin and boxmgmt without issue. I can also run get_vcenter_server_credentials and it displays the correct information.

Has anyone else encountered this issue? I'm not sure how to troubleshoot any further and am open to ideas.
