You might try n1uro.ampr.org on 44.88.0.9. It is usually there. Another AMPRNet host which is reliably there day in and day out seems to be kb3vwg-010 on 44.60.44.10. And as Marius says, yo2tm.ampr.org on 44.182.21.1.
Many AMPRNet hosts do not respond to pings (probably out of some mistaken idea that somehow enhances security) but do respond to telnet to their web servers on port 80.
A large number of bots seem to scan for port 80 responders rather than waste time doing ping scans these days. The popular 'nmap' utility does this too. I regularly see scans of the entire 44/8 address space probing for port 80. - Brian

44.0.0.1 can not be pinged via the tunnel, only via internet.
You need to try other tunnel endpoints, but really need to find a live one :-)
You could try 44.182.21.1...
