24.7 Production Series / OPNsense web gui through reverse proxy
« on: September 17, 2024, 03:53:08 am »
This seems to have just started happening with latest version. I have a proxy host setup on nginx proxy manager for opnsense gui https on 443. It all works fine except for one function. When I make a change that requires "apply" settings as opposed to just save, I get a "502 bad gateway." The apply does occur but when opnsense forwards back to the same page, it gets this error. Nginx logs show this.
[error] 2174#2174: *370905 upstream prematurely closed connection while reading response header from upstream, client: 192.168.x.x, server: fw.bxyz.net, request: "POST /interfaces.php?if=opt5&group=Force53_DNS HTTP/2.0", upstream: "https://192.168.x.y:443/interfaces.php?if=opt5&group=Force53_DNS", host: "fw.bxyz.net", referrer: "https://fw.bxyz.net/interfaces.php?if=opt5&group=Force53_DNS"
On the web client I only see the following error which doesnt really help.
Request URL:
https://fw.bxyz.net/interfaces.php?if=opt5&group=Force53_DNS
Request Method:
POST
Status Code:
502 Bad Gateway
Remote Address:
192.168.x.z:443
Referrer Policy:
same-origin
I tried changing read time out values, adjusting different settings in the admin menu in opnsense, switching to an http proxy host. Any help would be much appreciated.
