Hoping anyone can help me with this.

I run openproject in a docker container on unraid.

When trying to connect my sendgrid account to OpenProject (free edition) i get the following error:

"An error occurred while sending mail (Cannot assign requested address - connect(2) for "localhost" port 587)"

The log says the following:

App 427 output: method=POST path=/admin/test_email format=html controller=AdminController action=test_email status=302 duration=42.77 view=0.00 db=2.86 location=https://MYDOMAIN/admin/mail_notifications user=2
App 427 output: method=GET path=/admin/mail_notifications format=html controller=Admin::MailNotificationsController action=show status=200 duration=133.09 view=118.09 db=7.94 user=2

Any idea how to solve this?

Thanks in advance!

Hello,

It seems like you haven't properly set the SMTP server hostname. Maybe you can show a screenshot of your config (removing any secrets)?

You can also launch a console with docker-compose run web bundle exec rails c and then enter ActionMailer::Base.smtp_settings to view the configuration.
