I have tested the SMTP server with Telnet: Telnet connected to the SMTP server. Telnet allowed me to authenticate into the SMTP server. Telnet allowed me to successfully send an email using the SMTP server, and I used the exact same values in Telnet as are present in the /var/discourse/containers…

I’d suggest that it’s something about your setup that is broken, rather than bugs within Discourse. :wink:

Are you by chance using smtp-relay.gmail.com , perhaps from DigitalOcean? That seems to have broken recently and nobody is quite sure why yet.

No. Because the SMTP server is working perfectly as already described and Discourse is properly installed and properly returns the screen that prompts the admin registration email. However, that email does not send.

I am using a local SMTP server located on the same machine as the Discourse Docker container.

I found an error in /var/discourse/shared/standalone/log/rails/production.log: Rendering layouts/email_template.html.erb Rendered layouts/email_template.html.erb (Duration: 0.1ms | Allocations: 32) Delivered mail f915c15e-9c4d-4d4e-9527-81bc4984540c@forum.domain.com (63.7ms) Job exception: hostna…

[image] Hostname does not match server certificate installation Guys, I’ve tried all you have previously suggested but definitely I cannot succeed with that. Log says that the hostname does not match the server certificate. Any bit of help? Thanks for your time, it’s bit…

It appears the above error message is talking about the server ssl certificate. The ssl certificate on the server is correct and has the proper hostname. It looks as though this is a bug in Discourse, where Discourse cannot correctly detect the server ssl certificate.

This doesn’t sound like a bug in Discourse. It sounds like a problem in the host DNS resolver config or SSL certificate. Since telnet doesn’t use SSL, I guess that’s why you found that to work. Under linux you may find you can get a bit further testing using OpenSSL to test the connection and exa…

The https on the site is working because it shows the green padlock in the address bar. There is nothing wrong with the ssl certificate for the site. There is something wrong with the way Discourse detects the ssl certificate.

That error is not about the site certificate, but about your SMTP service certificate.
