The server side would give more information. If another port, besides 22, is available then spin up a one-off SSH server and record the output:
Code:
sudo /usr/sbin/sshd -d -d -d -E /tmp/ssh.session.log -p 2222
That'll set up a server listening at port 2222 for one session only, and the results will be logged to /tmp/ssh.session.log
Then try connecting from the problematic machine:
Code:
ssh -p 2222 manjaro.example.com
That session will be recorded in the temporary log file on the server and it will be much easier to read that way.
