How do you know those files didn't match? Were you able to log all the
way in and inspect them?

Bear in mind that creating an instance from a snapshot is not really
creating a 1:1 copy of the image. Behind the scenes, DO is almost
certainly doing other stuff (I don't know this - I am surmising).

If your snapshot has hardcoded network stuff - anything but DHCP - your
new droplet won't be contactable. The network interface names known to
the new droplet may be different from those of the original droplet,
again meaning you can't really hardcode anything and expect a clone to
work.

Finally, (and again I'm guessing) the new droplet probably needs new
access rules (if DO has external-to-the-droplet access controls).

Well - you can ping something that has the address you think the new
droplet has. How do you know the address you are pinging is that of the
new droplet? Networking in a virtual environment can be very funky.

Sorry, I'm not a DO user...
