504 Gateway Timeout

Support & Bugs
1

Hello,

We are currently in the process of upgrading Matomo to the latest version 3.13.5 (currently running 3.13.1)
after the deployment of the new version with nginx and php-fpm, the agents on the monitored sites show a “504 Gateway Timeout” error on the browser.

after inspection I found this error in the nginx error log:
2020/05/25 06:34:59 [error] 13715#0: *480 upstream timed out (110: Connection timed out) while reading response header from upstream, client: xx.xx.xx.xx, server: localhost, request: "GET /piwik.php?action_name=&idsite=xxxx&rec=1&r=379151&h=8&m=33&s=59&url=https%3A%2F%2Fxxx.xxxx.com&urlref=https%3A%2F%2Fxxx.xxxx.com&_id=xxxxx&_idts=1583823949&_idvc=80&_idn=0&_refts=0&_viewts=1590383892&send_image=1&pdf=0&qt=0&realp=0&wma=0&dir=0&fla=1&java=1&gears=0&ag=0&cookie=1&res=1536x864&gt_ms=184&pv_id=r361RB HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "piwik.xxxx.com", referrer: "https://xxx.xxxx.com/pdi/path/to/page"

This happened for all the monitored sites.
I tried running fastcgi using a socket instead of a fixed port but the same thing happened.

I also made sure that matomo.php is being executed.

I am using PHP 7.2.24 and nginx/1.16.1

Is this a bug in the new version? can anyone help?

Hi,

There is no known bug like this in the latest version and many people are already using it for a while.

Maybe updating takes longer than the max_execution_time allowed on your server and Matomo gets killed in the middle.
You could try updating manually instead:

Hi Lukas,

Thank you for your fast reply.

This is the link that I used for the upgrade.
I already tried increasing the max_execution_time but I still got the same error.
I Also tried removing and reinstalling Matomo

Hi,

Have you also tried running the update on the commandline:

./path/to/matomo/console core:update

Yes, directly after the upgrade and before I allowed the monitored websites to call the matomo server (agents were stopped using DNS)

Is there a way to see (enable) the php logs from piwik.php?
Can i redirect them somewhere to see them as the error is happening?

As for the max_execution_time, I set it to 300 (instead of the original 30). There is no traffic on the server so I don’t see why the execution should take that long.

Is there anything else I could do that might help?
