I have a strange issue here and wonder if someone’s random brainstorm might help me solve it!
For several years I’ve run a Discourse forum with no issues.
Suddenly in the last few days I’ve had errors in my Dashboard (and logs of course) showing that the Gmail POP3 password is failing (it’s been working for about 2 years and hasn’t changed) and also the SMTP connection to my paid delivery service (Postmark) is offering up a TCP Timeout (5 seconds?). Again the settings baked in from the
yml file have not changed at the server.
I also POP in to this Gmail account and send mail through Postmark on another Wordpress server and it’s working perfectly well from that second host machine (which has a different IP but is in the same datacenter) … ergo Gmail and Postmark seem fine.
I can’t send a test message from Discourse either.
To reiterate - this is not a new install with possible typos etc - it’s been working great for a few years with these settings.
And I’m on latest here at this time.
