Email Send Issue

[Max Schaefer]

First of all, thanks for open sourcing this tool! I really like using it to monitor my cron jobs 👍🏻

I've been having an issue with SMTP emailing, I have checked my user/pass and settings a few times and haven't been able to resolve it, other tools on the server work fine to send email with the same user/pass combo.

My ENV for Docker:

    environment:
      - DEBUG=False
      - DEFAULT_FROM_EMAIL=[e-mail]
      - EMAIL_HOST_PASSWORD=PASS
      - EMAIL_HOST_USER=[e-mail]
      - EMAIL_HOST=smtp.gmail.com
      - EMAIL_PORT=587
      - EMAIL_USE_TLS=True
      - SITE_NAME=Healthchecks
      - SITE_ROOT=https://healthchecks.excloo.com
      - TZ=Australia/Sydney

The error:

Exception in thread Thread-1:

Thanks for the report. Can you reproduce the problem with the official Docker image?

[Max Schaefer]

Yes, initially I was using that image (with identical settings) and had the same error, not entirely sure what’s going on - can try some tests if there’s any info
I can provide?

[Max Schaefer]

It seems to have fixed itself somehow, very very strange...

[Saqib Mehmood]

can i work on this bug?

[Saqib Mehmood]

anybody already working on this issue? Please let me know?

[Pēteris Caune]

@maxexcloo could it have been a case of you editing the wrong configuration file? Or perhaps the container not getting restarted and so using old values?

Is there something more we should do here, or can we close this issue?

[Max Schaefer]

Let’s close it for now, honestly not sure why it suddenly worked but maybe something was blocking the mail also - will close for now.
