There have been a lot of updates recently. One busted the subject line (no longer includes the category) and now no mail goes out at all. Users are very unhappy. I don’t know how to start debugging this issue. Where can I error logs and I recall there is some page about sidekiq queues and so on, but…

The cause of this may be sidekiq failing to process scheduled jobs when it should. We identified the same problem earlier today on our CD sites. Make sure you are at least the commit: https://github.com/discourse/discourse/commit/4394f5c17fa3db7ea9a44dba3f7de0ab9da036f5 (I think this is the commi…

Yeah, I’ve noticed that email notifications don’t seem to be firing at the moment after an update yesterday, although digest/summaries still are. Are we alone in this?

Yup, we were caught up in that. An update has sorted it.

I confirm hundreds of failed sidekiq jobs on latest-release +103 fixed on latest-release +153

I am updated to latest and am still having an email sending problem on one of my sites. I just get an error message when sending a test email. ERROR - end of file reached On mobile now we’ll check sidekiq and logs when I am at my computer. Any other suggestions where to look? ▶ Backtrace Just tr…

Hi Tobias! [이미지] tobiaseigen: Job exception: end of file reached … /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/net-smtp-0.5.1/lib/net/smtp.rb:1017:in `recv_response' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/net-smtp-0.5.1/lib/net/smtp.rb:676:in `block in do_start' Your problem i…

Hi Michael! Thanks for the response. I miss you guys so much! :smiling_face_with_three_hearts: Hmm.. I just moved my site from DO to Hetzner and it worked fine for a couple of weeks. My other site is working fine too. It’s a puzzle. Only sometime about a week ago it stopped working and when I looke…

I think it’s failing before even attempting login. To eliminate Discourse as a factor, try from the host AND from inside the container: $ openssl s_client -connect smtp.mailgun.org:587 -starttls smtp You should get a bunch of output and then be able to try to auth: ○ → openssl s_client -connect …

I tried swaks and got this: === Trying smtp.mailgun.org:587... === Connected to smtp.mailgun.org. *** Remote host closed connection unexpectedly. That inspired me to check from my other server, where swaks had “Great success” - the message is quite adorable! <~ 250 Great success ~> QUIT <~ 221…

[이미지] tobiaseigen: *** Remote host closed connection unexpectedly. Makes sense; this is essentially the same error as [이미지] tobiaseigen: EOFError: end of file reached As you suspect, the most likely cause is something external interfering with the connection.

i have a suspicion you need to use port 2525 instead of 587
