It should be fixed in current GIT master AFAIK -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1732671 Title: vnc websocket compatibility issue Status in QEMU: Invalid Bug description: WebSocket support in VNC should allow access from VNC client through upgraded WebSocket connection. This feature is not working in IE 11/Edge with noVNC HTML5 client, in contrast to that in Firefox/Safari, etc. The reason that IE 11/Edge fails to accept the connection upgrade is that the value equality of the `Upgrade` header field is checked in a strict case-sensitive manner in QEMU side, however, the IE/Edge does not send the exactly same string value `websocket` but a capital letter `W` instead. Defined in section 4.2.1 of rfc6455, the upgrade header field shall be treated case-insensitively. A patch shall be made in `io/channel-websock.c`, converting the value of upgrade string to lowercase before comparison is made with QIO_CHANNEL_WEBSOCK_UPGRADE_WEBSOCKET, to allow case-insensitive comparison in the process.
