Hello.
New day, new DPM problem:
Cannot protect one particular VM using host-level protection. It's the only VM having this problem. The error message (redacted names):
Affected area: RCT\<VMNAME> Occurred since: 24.05.2019 15:52:46 Description: The replica of Microsoft Hyper-V RCT\<VMNAME> on <HVHOST> is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent. For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106) The DPM service was unable to communicate with the protection agent on <HVHOST>. (ID 52 Details: The remote computer refused the network connection (0x800704C9)) More information Recommended action: 1) Restart the DPM Replication Agent service on <HVHOST>. 2) If <HVHOST> is configured using certificates, ensure that the DPM CPWrapper service is running on DPM Server and aof0078.ad.apponfly.com. Also ensure that certificates used by both the computers are valid. Synchronize with consistency check. Run a synchronization job with consistency check...

Can backup all other VMs on the Hyper-V host without issues. Hyper-V 2016 Server protected by DPM 2019. Previously protected by DPM 2016 UR7, where backup of this particular VM worked. HV hosts and DPM are in the same domain.
What I've tried:
- CC job - no good
- removed the protected DS and re-add it to DPM - no good. Actually the initial backup 'finishes' without a problem, but the backup has ~100MB (instead of ~40GB). RP count 0. CC job doesn't help.
- migrated the VM to different host - same issue
- 'reset' RCT (by shutting down the VM and deleting the .RCT .MRT files) - no good
- tried monitoring the DPMRA log during the backup attempt: this error comes out, however doesn't makes it any clearer:
