I am facing "ssh_exchange_identification: read: Connection reset by peer" error. I am not able to ssh my instance.
Any help is highly appreciated. Thank you. Below is the debug information

This actually happened quite a few times already. sometimes it happened once a day, sometimes weeks. I wasn't able to see any error logs.
What I had to do in order to fix is (rebooting never worked) to stop then start the instance.
I even tried launching another instance from a backup image I made awhile back then re-deployed my codes since all settings are the same, just need the new code then dns into this new ip instance. I tried using launching because there were at least two times the stopping took like 20 minutes and still saying stopping....so I launched a new instance. THEN this new instance have the same thing happen just out of no where that I can't ssh into my instance, site isn't running. So I had to do the previous steps again.
Any suggestion on what might be going on and how I can do checks?
