What are the steps to re-enable replication if replica-server lost the replicated vms?

Hyper-V reinstall solved this issue for us.

  1. Remove Hyper-V
  2. Delete Hyper-V files from C:\ProgramData\Microsoft\Windows\Hyper-V
  3. Reinstall Hyper-V

We use Certificate based authentication, so we had to create new certificate on replica server.

After these steps we was able to re-enable replication.
