I looked at my test server and found it has like this

```plaintext
nameserver 127.0.0.53
options edns0 trust-ad

```

So I followed that but still not working.

My thought is I changed `/etc/ssh/sshd_config` file to use ssh remote from my local PC  
Changed like  
` PasswordAuthentication no -> PasswordAuthentication yes`

Do you think this change might affect the server?
