Here in my company, we use a web application that started being blocked today by the Kaspersky Endpoint Security Web Protection Module. I got this error in the console:

WebSocket connection to 'wss://IP:PORT/' failed: connectXML @ VM47:1

I disabled only the Web Protection Module, and now the site is accessible. Does anyone know how I can fix this?
