I’m trying to replicate on Windows 10 but I can’t. Can you confirm that when you hit that page you send no search params?
My search params end up being something like this. Clearly something went wrong before we redirected you to no-VNC. The root cause is something more like ‘we didn’t generate url parameters’ instead of ‘you don’t have url parameters’.
I’m trying to track down how those URL parameters are generated and what may have gone wrong.
