Send SMTP Mail Message: An error occurred while attempting to establish an SSL or TLS connection

Hello,

One of the processes that been working prod for a long time started to get the error from Orchestrator>Logs Panel i shared below.
Can you help me with the issue to solve it.

Send SMTP Mail Message: An error occurred while attempting to establish an SSL or TLS connection. The server’s SSL certificate could not be validated for the following reasons: • The server certificate has the following errors: • The revocation function was unable to check revocation for the certificate. • The revocation function was unable to check revocation because the revocation server was offline. • An intermediate certificate has the following errors: • The revocation function was unable to check revocation for the certificate. • The revocation function was unable to check revocation because the revocation server was offline.

  1. Please try to disable the antivirus and firewalls and check if that helps
  2. In secure connection use starttls
