  3. Click on the vCenter client connection object and edit the client
  4. Verify the Avamar server IP or Hostname is valid
  5. Verify the vCenter user account that Avamar uses is valid

  7. Look at also restarting the MCS service on the Avamar server to clear any vCenter connection caching issues if the connection to vCenter was interrupted due to vCenter maintenance or network outage.
