Performance manual test deployment manager service task approval from email does not work

We have configured a deployment pipeline on Deploymen manager service.

In the deployment pipeline is set a “Perform manual test” task for approval, the user assigned to the task receive an email with the “Approve” and “Reject” button. When i click on approve, the deloyment pipeline is not resumed, still waiting for an action required.

The email i get from Deployment manager service is from “[email protected]”.

What should i check to fix this and be able to resume the deployment pipeline automatically when clicking on the “Approve” or “Reject” button from the email?

Regards,

Israel
