Cant acces via proxy after upgrade to 24 (Code 204)

Hello everyone,

I got the following setup:

I use nexctloud on my Raspberry Pi with php7.4 and Apache. The server is available from outside via NGINX reverse proxy on my Firewall
Since upgrading my Server from 23.x to 24.0.2, I cannot access the cloud from outside.
I haven’t change my config on either Apache or NGINX

On my Proxy I only see this error message:

*244 kevent() reported that connect() failed (61: Connection refused) while connecting to upstream, client: x.x.x.x, server:, request: "GET /index.php/204 HTTP/2.0", upstream: "", host: ""

HTTP Code 204 means → The HTTP 204 No Content success status response code indicates that a request has succeeded, but that the client doesn’t need to navigate away from its current page.

What has changed?

What is on your apache log?
