I am having an issue that NGiNX will stop running for no particular reason this causes Nextcloud to lose connection with Onlyoffice document server.

nginx version: nginx/1.18.0 (Ubuntu)

systemctl status:

Hello cahixiv.

The error looks similar to the one encountered by another user.

Try the described solution (unlink /etc/nginx/modules-enabled/50-mod-http-perl.conf) and let us know the result: Nginx exit with error code - #2 by Alexandre

NB! We recommend you to prepare whole server backup just in case.

I have done that and it is running so far. I did run the command:

root@onlyoffice:~# apt list --installed | grep onlyoffice
