Last update doesn't support $forward_scheme anymore

[devedse]

As of the last update everything broke as it seems it doesn't suppoprt the forward_scheme variable anymore:

a529a49 seems to have removed it

[Zoey2936]

yes it was removed

[devedse]

@Zoey2936 Ok so now what? What is the workaround then?

[devedse]

The issue is that the whole application isn't even starting, so I can't update the configs.

[Zoey2936]

the workarround is not using the varaibles at all, there is no reason to even use them. But you can try the last release, it should now only disable effected hosts

[Ryderjj89]

This was quite an unfortunate and seemingly unannounced change. I ended up fixing my hosts and not using the variables anymore but yeah. Luckily everything is back up for me.

[Zoey2936]

The readme describes how to configure many auth services, (anubis), tinyauth, authelia, authentic. All these examples are at least limited supported by me. If you need to input something inside a location, then this also possible using a custom location with its path set to /. So I don't see what usecase is there for this variables, even because they may were only be used in user provided configs, and I hope the uses itself knows to what theese were set.

[TheBlackBush]

Why these variables been removed?
I'm using the same template in Custom Nginx Configuration for a lot of hosts with these variables, can you bring back those variables?

[Zoey2936]

can show the error/what does not work?

[TheBlackBush]

the error is related to not been authenticated with authentik

2026/01/22 18:13:05 [error] 112048#112048: *124930 auth request unexpected status: 302 while sending to client, client: 10.100.10.***, server: invite.ibush.co, request: "GET / HTTP/2.0", host: "wizarr.*****.***"

[Zoey2936]

and the config is identical to the working once?

[TheBlackBush]

Yes

[Zoey2936]

can you maybe post the two generated config files for a working and a non working host?

[syphernl]

These variables allow people to apply DRY to their custom configs since the forward hostname and forward port is a setting in NPM.
Now if you ever need to change them you need to change it at multiple locations, which is not very practical.

[Zoey2936]

if want to input something into the location / you can do it this way

[Zoey2936]

1. you don't need to set the X-Original-URL, NPMplus does this for you
2. if you want to set additional headers using proxy_set_header you can still do this in custom locations
3. never user $http_host, always use $host / $host$is_request_port$request_port
4. these variables are redundant because of custom locations
5. why do I even write docs and examples if no one reads them and follows them?
6. Also in terms of nginx config, NPMplus is different from upstreams config generation in nearly every point (in terms of custom/advanced config), so guides written for NPM should never be assumed to work in NPMplus
7. I see the advanced tab as fully unsupported. But yes the removal of these vars is something that should have been mentioned in the changelog
8. I will lock this now, if someone has issues with the example I wrote in the readme for authentik I will try to help in a new/diffrent discussion
9. With the next release I plan to add a simple ui selection to enable different auth providers, including authentik
