Adding an important detail: it's seeing a 502 error; from the Safari console: - "There was a bad response from the server."

Hi all, I have a question: we've set up Guacamole for remote access, but we want to use it through Microsoft's Entra/Azure Application Proxy. Using it in this way always falls back to the HTTP protocol, websocket is not connecting with an error in the dev console (this is from Chrome, but the same counts for Firefox/Safari): "Websocket connection to wss://<edited-url>/guacamole/websocket-tunnel?token=<token>&GUAC_DATA_SOURCE=mysql&GUAC_ID=1&GUAC_TYPE=c&GUAC_WIDTH=1914&GUAC_HEIGHT=1626&GUAC_DPI=192&GUAC_TIMEZONE=Europe%2FBrussels&GUAC_AUDIO=audio%2FL8&GUAC_AUDIO=audio%2FL16&GUAC_IMAGE=image%2Fjpeg&GUAC_IMAGE=image%2Fpng&GUAC_IMAGE=image%2Fwebp failed" Connectivity to the backend is: Browser --> Entra App Proxy Service (cloud) --> App Proxy (internal component) --> Guacamole Server Does everyone run into this issue, while trying to make this setup work? Or does anyone have an idea on what could be wrong? Met vriendelijke groeten, Kind regards, David Paeme
