Based on the log I would say it should work:
SSH: agreed on: diffie-hellman-group-exchange-sha256,ssh-dss,aes256-gcm@openssh.com,aes256-gcm@openssh.com,none,none,
Would not know how to help further; TAC would be my next step, but if you don't have access it will be hard.
Maybe someone else has seen this and knows what to do. As you have seen the ssh traffic works in most cases, just not in in case and in one direction. You may try to open a case with Mikrotik as well, if you have access to that.

This might have to do with the limited SSH client in the switch, and a mismatch in supported ciphers between your switch and the Mikrotik. In general you should not SSH out from the switch, but must admit that it has become handy a few times in the past where I didn't have another device.
If you want to have this resolved, it's first important to understand why the session does not come up, and you might be able to configure additional ciphers in the Aruba switch, or in the Mikrotik. If you can't find out yourself, it would be best to work with TAC Support.
