The problem is that yesterday I could log in normally and so on. And since yesterday evening it seems as if something hung and I can't log into ftp (filezila) and putty at all.
When I try to log into ftp, something like this pops up:
Status: Connecting to cloud6*****9.nitrado.cloud...
Reply fzSftp started, protocol_version=9
Command: open "root@cloud6*****9.nitrado.cloud" 22
Error: Connection terminated after 20 seconds of inactivity
Error: Unable to connect to the server
And in putty there is a black screen and after a while Network Error pops up.
