Dear Discourse community, Im having problems with my instance of Discourse. Although the servers parameters didnt change, and I am able to use them e.g. via simple Python script, the Discourse fails to send emails. It happened all of a sudden about a month ago after an update. I have rechecked the…

Can you share your settings? (Makes sure you hide passwords though)

Hey, here they are: passwd is not needed, its a local server for internal use only: LANG: en_US.UTF-8 DISCOURSE_DEVELOPER_EMAILS: 'megan-community@informatik.uni-tuebingen.de' DISCOURSE_HOSTNAME: 'megan.informatik.uni-tuebingen.de' DISCOURSE_SMTP_ADDRESS: 'smtp.informatik.uni-tuebingen.de' # (ma…

Can you access github.com from your server (using ping or better curl)? Seems like a DNS issue or a network hiccup.

Thanks a lot for your answers! Unfortunately nothing changed. Ping works, DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4" is like its described. Docker was restarted, error when trying to rebuild remains the same,..

Unable to resolve host is definitely a DNS problem, if that is the error you are seeing.

It looks like two different problems. Google’s DNS may just help you to access the wild on Internet. It’s for access the web. For email sending, I am not sure how it works.[quote=“gvalchca, post:3, topic:43592”] its a local server for internal use only: [/quote] You have set a DNS record for yo…

its only for the network inside of the institute.

Did you try this? cd /var/discourse git pull ./launcher rebuild app And the only error you are getting is DNS correct? If so then DNS is definitely not working from your server. The launcher script does not require the smtp setting to have a password.
