[Spice-devel] Userquestion - remote-viewer connection fails with "Connection type could not be determined by URI"

[Stefan Silberstein]

Hello again,

so - yesterday I worked from home - as I wrote I was able to connect by
specifying the user root with "remote-viewer spice://
root at 192.168.178.51:5900"

Today I want to connect the exact same way (yesterday i simply closed the
remote-viewer window and the server keept on running so the windows-VM was
running the whole night) - and I can not connect.

Error Message on the console  "** (remote-viewer:6146): CRITICAL **:
07:55:52.853: virt_viewer_util_extract_host: assertion 'uri != NULL' failed"
Error Message on the popup says translated: Connectiontype could not be
determined by URI.

IP of the server itself is 192.168.178.51
IP of the Virtual Machine is 192.168.178.64 and i pingable
Port 5900 on the server is open: 5900/tcp open  vnc
remote-viewer --spice-debug spice:⁄⁄192.168.178.51:5900 does not produce a
more verbose output :(

Update in the meantime
But maybe this is helpful to you:

I simply started "remote-viewer --spice-debug"
Then i got the GUI (which i wasnt even aware it existed).

When I choose the same entry on that list - I AM able to connect.

So the error only exists only when I try to connect via command line?!
(This is when I am able to connect tomorrow via GUI ;) )

Shouldn't this be the same ?

I mabe I can help - maybe this is indeed a bug?

Stefan
