Hello All
Problem Description
I’ve been struggling with setting up Nextcloud behind an NGINX reverse proxy. My goal is to run Nextcloud in a subdirectory (/nextcloud) while using a reverse proxy to handle incoming requests. Despite following various guides and tweaking configurations, I am encountering several issues.
I’m relatively new to NGINX, but I’ve managed to fix the 404 errors for static files and the 502 Bad Gateway issue. However, I’m still facing problems with login page redirection, and I’m not sure where to start troubleshooting.
Before these issues, I was able to reach the Nextcloud install page and click the install button. However, I consistently experienced a proxy timeout screen during the installation process. Despite the timeout, I noticed that Nextcloud wrote the database configuration into config.php and observed some CPU activity, indicating that some installation steps were completed. Afterward, I couldn’t access index.php and was redirected to a 404 error page.
I feel like I’m missing something fundamental or misunderstanding some aspect of the setup.
- Login Page Redirection Issues:
- The Nextcloud installation appears to be complete, but when attempting to access the login page, I am redirected to
http://my-site.ch/nextcloud/index.php/login, which results in a 404 error. - It seems like the PHP files are not being executed properly, and the server is searching for static files instead.
2.404 Errors for Static Files: → Fixed with added nextcloud config overwritewebroot hopefully right approach
- When accessing static files (e.g., CSS, JS) through the reverse proxy, I get 404 errors.
- The static files are located in the
/var/www/html/nextclouddirectory in the backend container.

Troubleshooting Steps Taken
- Verified file and directory permissions.
- Ensured correct paths in the NGINX configuration files.
- Verified connectivity between the reverse proxy and backend server.
- Confirmed that PHP-FPM is running and correctly configured.
- Tried various combinations of
proxy_passandtry_filesdirectives. - Tried the example config from the Nextcloud documentation. I’m unsure about some aspects because I don’t want to create my own Nextcloud Docker image to have the Nextcloud folder inside my root like /var/www/html/nextcloud.
Questions
- My feeling is that
index.phpis not being executed anymore, and the server is looking for it as a static file. - Is there a better way to configure the NGINX reverse proxy and backend server to handle Nextcloud in a subdirectory? I switched to having two NGINX instances (one as a reverse proxy and the other as a web server) because I encountered other issues that I couldn’t solve.
Any help or insights from the community would be greatly appreciated!
