Need Help:Integration of Collabora Online with Web Application

Hi everyone,
I am trying to integrate Collabora Online with the dot net web application and wopi rest service. I have installed, configured, and hosted Collabora Online using desktop docker. But I am receiving the error messages

  1. “Wrong or missing wopisrc parameter please contact support”
  2. “Well this is embarrassing we cannot connect to your document”
    In the console, I found this “WebSocket connection to ‘wss://’ failed: Error during WebSocket handshake: Unexpected response code: 400”.
    If I am trying to browse only “”, I received the same.
    Collabora/code :latest
    OS: Windows 10

Thanks and regards,
Subhakar Mandal
