I tried different approaches found on the forum with no luck. I’ve seen empty welcome screen once and then after a few minutes ubuntu screen finally loaded but next time again session closed immediately.
I have quite high-end equipment (server and client) and 1Gbps LAN connection.
I do not know how to solve it…
