Hi I'm using Ubuntu 22.04 with newest Updates and newest ISPCONFIG3 Version. I also setup a KASM Server on a own VM. Locally with local IP's working well. Now i wanted to use it from outside behind ISPCONFIG3 as Reverse Proxy. I can connect to the Webpanel and do all work there. But if i try to start a connection it's not loading. - On DevTools i see: WebSocket connection to 'wss://F.Q.DN/desktop/e8eecc0d-...' failed: connect @ guac.js:13804 Failed to load resource: the server responded with a status of 403 (Forbidden) For me it seems that ISPCONFIG (Apache) do not Allow wss Request instead of https. Intresting for me: A Simelar Setup i use for Bitwarden installation. This uses ws (not wss) and this is working. Is there anything to allow wss or how i do I activate it? Thank you for any Tip
