Email secure

I have a Studio question on email. We are sending email notification using an SMTP server with port 25. In the connection details, there is an option for secure connection. We have had this set to “Auto”. Since yesterday, email will not send and gives an error. When we change the option to “None”, it works. I have tested email to the SMTP server with powershell and it works.

How would this have changed? What should I be looking at? All jobs are not sending notifications.

Here is a sample of an error message in the log.

Raw 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: • 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. MailKit.Security.SslHandshakeException: 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: • An intermediate certificate has the following errors: • The revocation function was unable to check revocation for the certificate.

I will have the user change this in the morning. I do not use the application on a regular basis. I am the tech support and learning how this works.
I have a few questions.

What would cause this to fail all of a sudden?
What is the CRL server?
I assume the user makes this adjustment on all their jobs. Is there a way to configure the email to be a “module” where they only have to make this change in one place and not in every job?

@dhodgkins

Firewall changes can effect it or even the smtp server also can

CRL is certificate revocation list which got revoked before expiry…

We use UiPath in the cloud. Does this make a difference?

@dhodgkins

crl etc are related to smtp servers and not to UiPath at all
