Use a port different from 443 on reverse proxy


I read the documentation but I still cannot figure it out.

I already use port 443 on my Synology and I plan to use the Synology reverse proxy, hence I need to use some other port.

How do I inform nextcloud that the reverse proxy is NOT using port 443? I could not find this information in the documentation.

Hi, can you follow

Thanks for the feedback, but there is nothing to troubleshoot, I just don’t know how to configure something. Specifically, how to configure AIO NextCloud to use a port different from 443 when doing its “self test” on the reverse proxy.

To elaborate, this is the prompt I see:

AIO is currently in “reverse proxy mode” which means that it can be installed behind a web server or reverse proxy (like Apache, Nginx, Cloudflare Tunnel and else) and does not do the TLS proxying itself.

Please type in the domain into the input field below that will be used for Nextcloud in order to create a new AIO instance.

Then I type

Then I see this in the logs:

NOTICE: PHP message: The response of the connection attempt to “” was: <html …

How do I get OIA nextcloud to attempt to connect to instead?

Ah now I get it. See GitHub - nextcloud/all-in-one: The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.

ah, I see. ok, I’ll have to find another software then. Wondering why though, is there a specific reason?
