thanks
that was the problem - no websocket connecction only http sorry for that - as i always setup websocket - but this time it was with univention ucs server and the guacamole cool solution there overwrites my proxy conf file without websocket section (i already informed them to change the guacamole.conf template) rg Christian Christian Kraus Inhaber CKC IT Consulting & Solutions e.U.

Assuming you are hosting Guacamole behind a reverse proxy, recheck your proxy configuration to make sure WebSocket is properly set up. Depending on your network, it is also possible that something between the client machine and Guacamole (such as a corporate proxy or firewall) does not properly support WebSocket and is forcing Guacamole to fall back to HTTP. - Mike
