How to fix error when connecting via VNC Viewer?

Question

linux

I try to connect to the server through VNC Viewer, specify IP:5900, then load ... and error: Timeout.

A day ago everything worked))

Through the hosting I launch the console and see that the desktop is working.

Any ideas where to look?

Answer 1

See how the VNC server is doing via ps and logs

Answer 2

Is vns. Whether precisely on this port. Is the firewall blocking?
Alternatively, kill the vns process, start it over again
