Veeam Backup & Replication • backup job email notifications not working consistently

Failed to send report to '<email address>'
[14.08.2024 19:45:29.302] <01> Error (3) The remote certificate is invalid according to the validation procedure. (System.Security.Authentication.AuthenticationException)


I see this randomly for config job backups as well as regular backup notifications.

I have been in and "re-setup" my smtp settings and saved them to reaccept the cert and that may or may not work for a few days. I don think this was an issue prior to 12.1. I am not sure what else to check. The email server used is not a public facing service like gmail etc. Its an internal sever.

Oddly sometimes it does allow emails through as expected.

I am out of ideas. I found a thread that talks about it maybe being related to TLS but i cant get to the article (KB2853) to confirm its related or not.
Also...the "test" email button works everytime with no issues.

What else can i be checking to get this resolved?
