Build-in CODE server doesn't respond after update to NC 21.0.4

[Sesivany]

I try to open a document and only get a grey screen instead of the Collabora Online UI. It started with NC 21, got fixed with the update of the server, and started occuring after updating to NC 21.0.4 and prevails on NC 22. Seems like the build-in CODE server is not responding, this is what I found in logs:

GuzzleHttp\Exception\ConnectException: cURL error 52: Empty reply from server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://www.example.com/nextcloud/apps/richdocumentscode/proxy.php?req=/lool/convert-to/png

A while ago the urls in the nginx and apache config changed, see https://sdk.collaboraonline.com/docs/installation/Proxy_settings.html#reverse-proxy-with-apache-2-webserver

Also recently the docker parameters changs, if you use those check those too, see https://sdk.collaboraonline.com/docs/installation/CODE_Docker_image.html

Is this really necessary for the built-in CODE server? I don't think so. That's what I'm running.
