The alarm "VXR034020 ALARM Remote connectivity lost" is observed when the VxRail manager loses connection to the DELL remote support backend.
The remote support connector on the VxRail Manager VM has lost communication with the Dell remote support backend, preventing automated health.
This is a proprietary alarm originating from the Dell VxRail orchestration layer, rather than core VMware software.

The remote support connector on the VxRail side has lost the connection with the remote support backend.
This is a connection from the VxRail to the DELL side and needs to be investigated by opening a support case with DELL. When this occurs DELL will not be informed of any errors and will not contact you since the remote connectivity is down and they won't automatically see this alarm. A manual ticket is required to restore your support connection with them.
The below steps can be quickly checked to see if they reset the connection. If they do not resolve it open a case with DELL and use their KB link below.
