Hello,

I installed and configured OpenProject on CentOS8 and the problem I am facing is that email notifications are not working. I setup the "Email notifications" and when sending mail manually, I receive it. Not sure if I need to configure or change something about the delayed_job or the problem is completely different ?! Here are some checks and logs from my investigations:

• Checking the count of the delayed jobs:

[root@GVA-LIN-ITMS01 openproject]# openproject run console

Loading production environment (Rails 6.0.3.4)
irb(main):001:0>
irb(main):002:0> Delayed::Job.count
=> 5
irb(main):003:0>

• The error I receive when checking the status of the delayed_job

[openproject@GVA-LIN-ITMS01 bin]$ ./delayed_job restart
Traceback (most recent call last):

Thank you in advance!!!

Let me also share my smtp an configuration.yml files and the output of "openproject run check"

Thanks if someone can help on this! Trying to send a mail from the Web UI works just fine.

On Ubuntu 20.04 on a Digital Ocean droplet I also have this issue:
irb(main):002:0> Delayed::Job.count

It seems the packaged installer did not install any cron jobs.
I tried adding them manually but I got the error:
/bin/sh: 1: /opt/openproject/.rvm/gems/ruby-2.1.5/wrappers/rake: not found
And indeed I I could not find the .rvm directory

bundle exec rake jobs:workoff
gave Command 'bundle' not found, but can be installed
So I installed it using: apt install ruby-bundler
Now when I run bundle exec rake jobs:workoff

I get the error:

Your Ruby version is 2.7.0, but your Gemfile specified ~> 2.7.1

@Mario : the environment variable is supposed to be SMTP_USERNAME. Did you manually override your config in /etc/openproject/conf.d/smtp ?

@Johnny: background jobs are not handled by cron jobs, but by a worker daemon. Can you check service status openproject-worker-1?

Hi Cyril,

Yes indeed.. when installing OpenProject, I didn`t put the actual mail server settings and afterwards I tried to correct this manually from the /etc/openproject/conf.d/smtp file. Instead, I should have just run openproject reconfigure which I finally did and followed by restart it solved my problem. 

Thank you for your prompt reply!
