Error mail flask worker

[maximushugus]

I have issues trying to send mail with Fittrackee.
As I said in another issue witch is resolved, I installed Fittrackee using this container.
I'm able to configure the EMAIL_URL variable without any error when I launch Fittrackee.

When trying to send mail, nothing happen so from inside the docker container I tried this command : flask worker --processes 2 and I tried again to send mail.
This time, in the output of the previous command, I get this error :

2023/11/01 23:43:42 - dramatiq.worker.WorkerThread - ERROR - Failed to process message account_confirmation_email({'language': 'fr', 'email': 'test@test.fr'}, {'username': 'divers', 'fittrackee_url': 'https://test.fr', 'operating_system': 'Windows', 'browser_name': 'Firefox', 'account_confirmation_url': 'https://test.fr/account-confirmation?token=qFtf6cAZFUFmz5Al2ksJCXXvjL3Bzip1bAUBlWYm'}) with unhandled exception.

    sock.connect(sa)

I do not understand what is the problem.
Could someone give me help ?

Thanks !

Hi,

sorry for the delay.
can you check if the mail server is reacheable from the container?

[maximushugus]

No problem.
Yes from the container I can access the mail server (I can wget a HTML page on the same server).

[SamR1]

OK, thanks for your reply. Have you tried using the mail server port?

[maximushugus]

If you mean specifying the email server port in the EMAIL_URL variable : yes, I use port 587.
I also tried from a shell inside the container to do wget mail.example.fr:587 and I can access the mail server as I obtain a response 220 ...

Hi,

Thanks for your answer.
I have set up a new instance with the same docker image and an SMTP server (EMAIL_URL=smtp://username:password@smtp.example.fr:587?tls=True). Emails are sent without error.

Maybe the SMTP server is blocking the connection?

For information, a CLI is available, especially for single-user instance (it allows to configure FitTrackee without an SMTP server).

I do not know if there was an update on this container, but today, if I run from inside the container the command flask worker --processes 2, I receive mail. I was not the case 2 weeks ago.
Problem solved
