Hi,
I have a dedicated server with NX NoMachine installed. I've configured it once and it has been working for over a year without a single problem. During that time the server was updated and restarted several times, but the NXSERVER has never failed me... until now. It just stopped working... I read all the forums regarding this problem, but nothing has helped. I uninstalled it and installed it again, I changed ssh keys, I fixed some symbolic links (there were some problems in lib directory), but today I ran out of ideas what to change in order to get it working again... Please help! Any hints will be much appreciated!
