Onlyoffice Nextcloud behind a reverse proxy

Hi All

Have a mature NC28/Ubuntu22LTS/PHP8.3/MySQL10/Nginx that is functioning correctly behind an Nginx proxy server serving LetsEncypt certs.

I installed Onlyoffice Community/Ubuntu22LTS on a separate machine behind the same proxy server.

The proxy is setup correctly to allow OO into the LAN. But I am having nginx configuration issues on the OO server. I installed OO using the onlyoffice website install guide. Cannot get nginx to start and run.

I have been editing the “/etc/nginx/conf.d/ds.conf” file, but it still won’t run.

Wondering if anyone has a generic nginx file contents that I can use to populate it and start editing it from there? Cannot find a good answer in the searches.

Regards
