Sometimes I switch between putty and working directly on the pi (with an extra monitor). This time I used putty and typed in "logout" by mistake. Putty closed immediately.
Then I tried to open a new session with putty as I do before.
I got the error
"Network Error: Connection refused" in a pop up window.
So I connected the monitor and entered
raspi-config, thought the SSH remote access was disabled.
But when I'm trying to enable it I get the error
"There was an error running option A4 SSH". The same comes up when trying to disable it.
What happened here and how can I reactivate the remote SSH access?
