I have set up absolutely everything, and my domain allows you to access the application and everything works great in the desktop browser - thanks for this opportunity!
But as soon as I try to open the same link via webview, it starts swearing at headers...
What am I doing wrong?

Look, I added cors almost everywhere, hahaha: to the nginx configuration, to my backend, and even to the godot project itself (a module from official addons that puts them automatically, which by the way does not help at all).
For some reason, the desktop browser opens great.
Do you think that you need to make settings with webview?
I'm already leaning towards this, too, because I've tried all the settings in the backend and unity html projects open normally.... What settings do you think I should enable in the webview?
