Loxone webinterface and websocket

traxxus

Hi

I am using the transparent webproxy with Sophos UTM 9.3.

When i try to access an Loxone(1) webinterface (Port 80) i can open the page and type in the credentials, but login is not possible.

Chrome debug says: 

WebSocket connection to 'ws://xxx.xxx.xxx.xxx/ws/' failed: Error during WebSocket handshake: Unexpected response code: 400

There are no errors or blocked pages in the proxy log. It just don't work.

Disabling the web proxy is the only cure. So i think it's an bug in the UTM web proxy. I can't contact the support, because i am an home user.

If an Sophos employee or forum mod want to test this for debugging, send me an PM/email so i can send you the website with the credentials.

(1) Loxone is an self hosted home automation server.

    This is more likely an error at XXX.XXX.com, Gustavo.  Here's what 405 means:

    405 Method Not Allowed

    A request was made of a resource using a request method not supported by that resource: for example, using GET on a form which requires data to be presented via POST, or using PUT on a read-only resource.
