Hi Stefan,
Sorry for delay in responding to your post. As you
would have noticed recently we have introduced HTML viewer under
Remote Control feature. For this action, 2 additional ports
i.e Ports 8081 and 8082 are introduced using HTML5 viewer websocket
connection in backend.
We have also captured the information in below KB
article :
Error message "Web Socket Connection terminated.
Error: Abnormal Closure: https://www.manageengine.com/products/desktop-central/knowledge-base/html-5-viewer-remote-connection-error.html
Let me know if you need further clarification.
Appreciate your patience and understanding.
Regards,
