The SSL certificate on the mail server which one of my Discourse instances appears to have an issue.
I only saw this because went to /logs and viewed:
Job exception: SSL_connect returned=1 errno=0 state=error: certificate verify failed
The detail is:
/usr/local/lib/ruby/2.3.0/net/pop.rb:553:in `connect' /usr/local/lib/ruby/2.3.0/net/pop.rb:553:in `do_start' /usr/local/lib/ruby/2.3.0/net/pop.rb:531:in `start' /var/www/discourse/app/jobs/scheduled/poll_mailbox.rb:41:in `poll_pop3' /var/www/discourse/app/jobs/scheduled/poll_mailbox.rb:16:in `execute' /var/www/discourse/app/jobs/base.rb:153:in `block (2 levels) in perform'
I would have expected this to show in
/admin just like we see sidekiq errors when those are present.
