Hey, so today I additionaly installed node red to my server (just a side note). So after everything and i wanted to reconnect to my raspberry pi 4 running ubuntu server I could no longer do so, and I m getting the following error:

ssh: connect to host 192.168.178.64 port 22: Connection refused

When I trie to connect over my phone everyting works and I also can no longer view the nc web interface. Has anyone experienced these problems?
thanks

Do you have fail2ban running? It already happened to me that I was locked out by it.

3

yes but in the jail.d folder are no more files

4

And this:

sudo fail2ban-client banned

is answering the same?

oh yes there is one in, how can I delete it?

6 
sudo fail2ban-client unban <IP>

or

sudo fail2ban-client unban --all

Hope that helps,
much luck!
