Cant ssh to droplet after setting ufw rules

Posted on July 8, 2021

Created a droplet 1w ago, everything was fine. But yesterday, after creating ufw and allowing port 4000 (i think) I am unable to login back to ssh.

root@ubuntu:~# ufw status
Status: active
To                         Action      From
--                         ------      ----
4000/tcp                   ALLOW       Anywhere                  
4000/tcp (v6)              ALLOW       Anywhere (v6)

This was executed then before closing my terminal. Now:

user@machine:~$ ssh root@46.101.110.x

Hi @ykostov,

For such cases, I’ll recommend using the Recovery Console. The Recovery Console provides out-of-band access and is available regardless of your network settings. It emulates the access you would have if you were sitting down with a keyboard and monitor attached to the actual server. You can use this feature to log in and revert bad settings to regain normal access.

You can read more about how to connect using the said console here:
