Title: Nginx and opnsense.domain "Server Error ...."
Post by: danman on August 16, 2026, 03:08:11 AM
Hey

I'm currently setting up opnsense with nginx.
I've already set up ACME which works fine and now I'm trying to use opnsense.domain instead of 192.168.20.1:10443.
Which means I changed GUI port to 10443 and disabled web gui redirect. I deleted LAN and created a bunch of VLANs and 192.168.20.1 is one of it.

I created an upstream server (not mentioned options means defaults):
Description opnsense.domain

Server 192.168.20.1

Port 10443

Server Priority 1

upstream
Description opnsense.domain

Server Entries opnsense.domain

Enable TLS (HTTPS) enabled
 

Location
Description opnsense.domain

URL Pattern /

Upstream Servers opnsense.domain

Force HTTPS enabled

HTTP Server

HTTP Listen Address 80

HTTPS Listen Address 443

Server Name opnsense.domain

Locations opnsense.domain

TLS Certificate opnsense.domain (ACME Client)

HTTPS Only enabled

The error is:
Server Error

Sorry, but something went wrong on our side.

There is nothing you can do except waiting until we fix the issue.

I didin't do anything with Naxsi if it is related to that?

Hope someone can push me to the right direction.
