504 after survey submission with participants/tokens table was created by QuoTil
Hi folx,

We're experiencing a major issue after the update to 3.14:

If it is a closed survey with participants/ tokens the submission of the survey ends with a 504. The user never reaches the "Completed View". This LS-behavior is not seen when the survey is open to everybody (without participants table).

Immediate help is needed.

504 : Gateway Time-out

Check your webserver log, can be different things …

Try to activate debug mode, and try with a little survey.

Any idea?

1. Which version was used before the update to 3.14?
2. Nginx error. Can you post nginx.conf and tell us a bit about your setup. You can click on the version number at the bottom of your LimeSurvey installation to get systeminfos.

My apologies.

DevOps did cut off the email configuration (server/firewall-side). It seems that this blocked the completion of the survey. As much as I could see the debug mode did not report this as an error - which would be nice. Also maybe it would be an option to let LS complete a tokenized survey even if the email configuration fails.

Anyway. Sorry again and thank you for your great work.

That might be the case. I guess you wanted to get an email after each completed survey sent to you? To me this looks like a timing issue. The email couldn't be sent and is causing a delay (still room for improvement for LS devs). The NGINX timeout is lower than the delay caused by LimeSurvey handling the email error.

No, because it can be easily fixed with a good mail server.
You can use your own server as a relay, mail is send by your server but it take really less time to send via PHP

No room for improvement, really? The error handling, when a survey is submitted and an email is triggered for the admin, might not slow down the submitting itself.

It might, but it shouldn't. ;-)

This comes from trying to be more polite ;-)


When a mail cannot be sent, the submitprocess should continue. Without having a task queue a bit difficult to implement. Experience of survey respondent is more import than a missing email for the LS user.
