Hi since today my node is suddenly offline. Internet connection is working and nothing happened.
If i want to log in with Putty i get Network error.
How to solve?
There are many potential causes for one to lose ssh connectivity to a computer one previously was able to connect to. The computer may have crashed, the sshd server may have crashed, the router may have changed the local ip address of the computer, or the ISP may have changed the public ip address of the modem.
