When on the server i can login to localhost using:

ssh localhost    
username@localhost's password:  
Welcome to Ubuntu 20.04.3 LTS (GNU/Linux 5.11.0-40-generic x86_64)

However when I try and login remotely i get this:

ssh 1.2.3.4 -l username
username@1.2.3.4's password:
Permission denied, please try again.

The password is absolutely correct.

Edit: I added the verbosity to the client login and this is the output after entering the password

debug3: send packet: type 50
debug2: we sent a password packet, wait for reply
debug3: receive packet: type 51
debug1: Authentications that can continue: publickey,password
Permission denied, please try again.

(a) is "username" actually "root"? (b) are you using the correct IP address? – Chris Davies May 04 '22 at 15:04
Did you check the logs of sshd? – Bodo May 04 '22 at 15:10

Use this answer to fetch public host keys from the server in the two cases. If the responses don't match (note: the order of lines doesn't matter) then it's not the same server (maybe remotely you're connecting to the ISP's server?). – Kamil Maciorowski May 04 '22 at 15:16
Use ssh -v ... to get more information. – waltinator May 04 '22 at 15:27
@roaima No its not root – CathalMF May 04 '22 at 15:43
@waltinator I updated the question with the output from -vvv after entering the password. Doesnt help much. – CathalMF May 04 '22 at 15:49
@KamilMaciorowski It is the correct server. – CathalMF May 04 '22 at 15:50

You haven't mentioned the server OS or Distribution. If it has /var/log/auth.log or /var/log/secure please add the lines tagged with ssh to your question. If it doesn't have this file please check other recently modified files in /var/log for entries tagged with ssh – Chris Davies May 04 '22 at 16:18

FYI- you might want to obfuscate your IP address since it's public. – clownbaby May 06 '22 at 16:29
Any information from the server logs? Those will explain the reason, whereas client logs will only show a simple refusal – Chris Davies May 06 '22 at 17:18
Have you edited /etc/ssh/sshd_config at all? – Chris Davies May 06 '22 at 17:19
