To get around this with the OpenSSH client (ssh command), you simply need
to add the flag -o PubkeyAcceptedAlgorithms=+ssh-rsa
to the start of your ssh command, which will tell your SSH client
to trust ssh-rsa and should allow you
to connect: ssh -o PubkeyAcceptedAlgorithms=+ssh-rsa -p 2222

to search online...
