My previous installation had issues with the TLS certificate time of issue, which was successfully fixed in this version (https://bugzilla.redhat.com/show_bug.cgi?id=1210486). However, when trying to start the SPICE HTML5 client, all I can see is the grey square and no activity, and when clicking on "Toggle messages output", the error message "Unexpected protocol mismatch" is shown.

However, the keystrokes indeed seem being sent because if I close the HTML5 client and reopen it, I see what I typed before I closed it. The messages output shows something like this:

Hi Nicolás,
good…so then it sounds more like a problem of spice-html5…you can try downgrading that too
hm..doesn't sound like the web clients are progressing in the right direction :-)…well, that's the reason they are still considered experimental and when possible you should rather use remote-viewer.

Jakub was trying that yesterday…did it work for you?

Thanks,
michal
