**Hardware:** VPS bought online ( Contabo )
**YunoHost version:** 11.1.0.2 (stable)
**I have access to my server :** Through SSH and browser
**Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?** : no
hi!
im trying to sync a directory from my machine to my yunohost servers but, with either `scp` or `rsync` i always get the same error:
`ssh: connect to host mms.nohost.me port 22: Connection refused`
the port is present and open in the firewall section.
anyone can help? đ¤

sounds like you tried multiple time to connect with incorrect crendentials and got (temporarily) banned by fail2ban âŚ
(Though could be something else too)

it happened since the first attempt, but probably this fail2ban issue is related to [this](https://forum.yunohost.org/t/postfix-smtp-server/22854)? i received around 10 more similar emails overnight.

i checked already and fail2ban is working.

i did it anyway, but a couple of warnings came up:
```auto
Info: Saving the new configuration...

Success! Configuration updated for 'fail2ban'
Warning: Job for ssh.service failed because the control process exited with error code.
Warning: See "systemctl status ssh.service" and "journalctl -xe" for details.

Success! Config updated as expected
```
[this](https://paste.yunohost.org/raw/dekirutike) it the log.
and eventually the port hasnât been changed and the ânew oldâ one doesnât seem to work anymore. đ

In the log, I saw you used a port outside the range permitted.

guess that might have caused the error, but now neither of the two works.

by accessing Tools through the web browsser portal i can get [the logs](https://paste.yunohost.org/megahexuqu) of `ssh`, which status is _failed_ btw.

Now you 're locked out of your server. I donât know if you have an emergency access on your vps, that would be helpful to restore the port to 22, restart sshd. Or you can try a terminal app on yunohost.
After you get a working 22 port, change it using [Security | Yunohost Documentation](https://yunohost.org/en/security?q=%2Fsecurity#modify-the-ssh-port)
Test it and close port 22

Seems we have a bug here. security.ssh.port must not be in the wrong range
> sshd[1268424]: /etc/ssh/sshd\_config line 7: Badly formatted port number

i do, it gave me root access through ssh but now im not sure how should i restore the port.
i found this online:
```auto
rm /etc/ssh/ssh_host_*
dpkg-reconfigure openssh-server
```
is that correct?
