502 Gateway Time-out

[Crashone]

Describe the bug

Each time I navigate through files via the web interface, Nextcloud server is no longer responding and ended with a 502 Gateway Time-out :

Other applications are not affected, and I can still connect to Yunohost web interface.

Context

• Hardware: OVH VPS
• YunoHost version: 11.2.5 (stable)
• I have access to my server: Through SSH and through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: NO

Logs

/var/log/ngnix/MyNextcloudURL-error.log :

• 2023/11/10 23:33:51 [error] 1191#1191: *4386 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 2a01:cb14:aa7:6e00:f1a3:48a9:d78b:98f8, server: MyNextcloudURL, request: "GET /index.php/204 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php8.2-fpm-nextcloud.sock", host: "MyNextcloudURL"

Can you check that the service php8.2-fpm is up and running (in Tools > Services)

Yes it is.

Here the full log : Nginx : https://paste.yunohost.org/vikahiyoxu

php8.2-fpm https://paste.yunohost.org/aduwefavop

php only indicates "[10-Nov-2023 23:56:37] WARNING: [pool nextcloud] server reached pm.max_children setting (8), consider raising it". If I restart php8.2-fpm, I can access to Nextcloud, but the server crashes again as soon as I start navigating through files.

Yes happens to me too. You have to increase some numbers. Go to /etc/php/8.2/fpm/pool.d and edit the file nextcloud.conf.

pm = static
pm.max_children = 100
pm.max_requests = 500
request_terminate_timeout = 1d

I added pm.max_children = 100 and with my server's resources it works well. Test to see how much you need. Make sure to restart the php-fpm after you do any changes in order for them to take effect.

Thank you for this solution.

Closing because the issue appears to be fixed by tweaking the pm settings
