I tried everything you suggested and nothing worked. I re-imaged the sim card but it is still doing the same thing. I tried another Sim but again the same result. Different computer, same result, different cord connecting printers and pi, didn't work. Differnt power source, didn't work.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!

It is also possible that a host key has just been changed.

The fingerprint for the ECDSA key sent by the remote host is

SHA256:9Ky3VtX22T5sWUldoVYToSYAz7Ca2kvARdmkHjhWE4Q.

Please contact your system administrator.

Add correct host key in /Users/Drewboy/.ssh/known_hosts to get rid of this message.

Wait.... you are not able to SSH into the machine but are telling me you tried all points outlined in the FAQ, some of which require you to SSH into the machine, and they didn't work? Care to explain how that can be possible?

In any case...
