Droplets failing regullary

I'm experiencing problems with droplets in third time.
Having a droplet set up from a base image (ubuntu 14.04 with lemp) running for a while and without any changes to system:

  1. Droplets change their RSA fingerprint with time. More or less often. This is not normal.
  2. ssh-key auth stops working. SSH begins to ask password (that I don't have). And after reseting root password via admin panel - new root password doesn't work too. After restart Mysql also failed. Console access also stopped working.

Again: this is not first droplet that fails like this and I do not do any changes to system.
This is VERY confusing and with such fails I just can't use DO in production.
This needs some reaction from DO support.

Hi there!

You're right, the host keys changing constantly is definitely not normal. Are you by chance logging in with a hostname instead of the droplet IP address? My concern here is that maybe you're intermittently resolving the hostname to a different IP address and perhaps not always connecting to the same server.

As for MySQL failing, that would likely be a different issue and should be approached from a separate angle than that of the SSH host keys.

As for the console, what happens when it stops working? Do you get any error messages?

If I can be of any further assistance, please be sure to let me know.

Kind Regards,

Not working console means that it requires root password and that was sent be reset is not accepted
