One site will not work through Zoraxy

[ckvist72]

Hi.
I have moved all from Nginx to Zoraxy. And everything works. Except my proxu for Opnsense... It hust says bad request. - Any idea if i have missed something.

@ckvist72 I never used Opnsense but from its documentation for reverse proxy, seems you will need to change something in their system settings to make it works. Try the followings

1. Make sure your Opnsense is running under HTTP or HTTPS with a valid certificate
2. Check "Skip certificate validation" in Zoraxy if your Opnsense instance is using self sign certificate with https
3. Check your settings in Opnsense to make sure it accept the hostname you are using as one of its up(down)stream

Hello, I'm currently facing the same problem. I've got all servers running except OPNsense. Is there a solution here by the time this post was written?

Exactly the same problem.

1. Make sure your Opnsense is running under HTTP or HTTPS with a valid certificate - I have already a certificate with the ACME Plugin in the OPNsense.
2. Check "Skip certificate validation" in Zoraxy if your Opnsense instance is using self sign certificate with https - is checked
3. Check your settings in Opnsense to make sure it accept the hostname you are using as one of its up(down)stream - is entered in "Alternate Hostnames"

I didn't have to change anything special in the OPNsense config in the nginx proxy manager, so I'm surprised that it doesn't work with Zoraxy

In fact it is another way round. Since nginx is much older than Zoraxy, many open source project use it (and Apache) as the compatibility test proxy when coding their web ui. I design Zoraxy to work in my homelab, so it might not fit everyone's needs.

However, you can help to make Zoraxy supports Opnsense if you could maybe provide a bit more hints on what errors you encountered like network traces or wireshark captures.

I also think that it is the OPNsense problem, perhaps I have ticked a box incorrectly. When I click on the link in Zoraxy under HTTP Proxy, I am correctly redirected to the OPNsense Web GUI. If I click on the domain name via Zoraxy instead, a bad request page appears.

Here ist a screenshot, all other settings are default...

I don't see any problem with your setup. You probably go create an issue on OPNsense's side and ask for their maintainers opinion on this.

Maybe this sheds some light on it:
