Key not present on hopeful-pig -- pushing

Description

I am trying to use a Coral mini board from my University and when I try to run "mdt shell" on my Windows PC, I am getting this error

`Waiting for a device...
Connecting to hopeful-pig at 192.168.101.2
Key not present on hopeful-pig -- pushing

Couldn't connect to keymaster on hopeful-pig: [WinError 10061] No connection could be made because the target machine actively refused it.

Did you previously connect from a different machine? If so,
mdt-keymaster will not be running as it only accepts a single key.

You will need to either:

1. Remove the key from /home/mendel/.ssh/authorized_keys on the
   device via the serial console

• or -

  2. Copy the mdt private key from your home directory on this host
     in ~/.config/mdt/keys/mdt.key to the first machine and use
     'mdt pushkey mdt.key' to add that key to the device's
     authorized_keys file.

Failed to push via keymaster -- will attempt password login as a fallback.
Can't login using default credentials: Bad authentication type; allowed types: ['publickey']`

I have found the private key on my host computer but I am not able to push it on to the board and when I try mdt push mdt.key I again get the same error as above
