I am connecting to a gmail mailbox using an email port in IS 9.6.
The certificates have expired recently and I started to have Certificate errors in the log. So I’ve placed the new certificates in the truststore and removed the old ones.
The mail port now gets connected, the emails are retrieved, everything seems to work but once in a while I have a “Certification chain trust verification failed” error message and the email port gets disabled.

If I try to connect the mail port again, sometimes I get this error
Failed to start EmailListener:pop3s:@gmail.com@pop.gmail.com: [ISS.0070.9003] Enable failed: Could not log into account @gmail.com@pop.gmail.com
But after editing the email port configuration, for example if I enter the password again and save it, it gets connected again. After a few emails are successfully retrieved from the mailbox, after around 20 or 30 minutes, it gets disconnected again.
I would expect the email port to either always work or never work if the certificates were wrong.
But having this intermittent behavior is making it hard to find the real reason why it’s failing.
I have only faced this problem after the certificates have expired. Before that, I had it working with no issues for around 4 months.
Has anybody faced an issue like this?
Thanks,
