[X2Go-User] X2go session won't connect

I've been wrestling with a strange error that only seemed to be affecting my Linux laptop (OpenSUSE Tumbleweed), connecting to my Linux server (OpenSUSE LEAP). Sessions seemed to start, but wouldn't connect. If I tried to connect a 2nd time, it appeared to offer me an existing session, but would not connect.

The client scrolled errors related to "unknown remote host 'localhost', and "unable to resolve remote host 'localhost'.

Turned out I had removed the localhost entry from my /etc/hosts file.

/etc/hosts 127.0.0.1 localhost

Adding this back, fixed this problem.

I'm sending this email in case it is helpful to others. I couldn't seem to find any documentation mentioning localhost.
