Symptoms

After update of Storage Node and Agent to Update 2 (Build 26981), backup to a managed location fails with the following error:

Failed to connect to the storage node. SocketError: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed

Cause

The hash of ASN server certificate stored in agents is not changed. The one that can be changed is the ASN certificate. If the ASN is uninstalled and then reinstalled, then it'll generate a new certificate. And the new one won't match the stored in the agent, so the agent won't be able to connect to ASN.

Solution

The issue is resolved in Acronis Cyber Protect 15 Update 2 (build 27009). 

Workaround

If the problem reproduces in newer build versions, use one of the workarounds described below.

Workaround 1

To remove the stored certificate hash from the agent, remove the Acronis Storage Node backup locations and add them back:

  • Go to the Backup Storage view and remove the Acronis Storage Node location,
  • Add the location again.

Workaround 2

If the first solution didn't help, the stored certificate hash needs to be removed manually.
