[BUG] Ui to standard when Authelia is used

The bug

Thanks for UpSnap!

I'm using it on Docker with NPM (NGINX Proxy Manager) and want to use it behind Authelia as an additional layer of security.

However, when I add the Authelia code in NPM, open UpSnap via it and log in, the UI appears, but without my set up devices (+ my favicon is gone). When I remove the Authelia code again, everything loads normally again. Apparently UpSnap is not compatible with Authelia.

Since I don't know how UpSnap works, I hope one of you can tell me which part of Authelia (see below) is interfering with UpSnap.

This is the Authelia config for NPM:

include /snippets/authelia-location.conf;

location / {
    include /snippets/proxy.conf;
    include /snippets/authelia-authrequest.conf;
    proxy_pass $forward_scheme://$server:$port;
}

I have attached the files mentioned in the script. (I have renamed it to .txt so that GitHub will accept it)
authelia-authrequest.txt
proxy.txt
authelia-location.txt

I am very grateful for any help! <3

i was able to further identify the problem. it is due to the following line in "authelia-authrequest.conf":
auth_request /internal/authelia/authz;
the command ensures that users have to log in if they are not logged in.

In addition, here is the error from the browser console:

(these are the lines mentioned in the error. once underlined in red and once marked in blue)

I hope that someone can help me!

Haven't used authelia yet, but make sure websockets are working. That's what upsnap relies on.
Also try 4.2.13-beta.2 as this fixed an issue with settings_public which you also mentioned.
