Unable to connect to EC2 server with my MacBook – CentOS

I am unable to connect to EC2 (CentOs) from my MacBook. When I connect it from ubuntu machine, it will be connected. Currently, I got the following the following error:

ec2 ssh sign_and_send_pubkey: no mutual signature supported Account locked due to 290 failed logins

How can I solve the problem?

I have tried the following command:

ssh -i key.pem ec2-user@ip

    Host *

    I was locked out and couldn’t access the machine to enter in the suggested answer’s change to ssh config.

    I added the following argument to the ssh call -o PubkeyAcceptedKeyTypes=+ssh-rsa and it worked.

    Example:

    ssh -i "keypair.cer" -o PubkeyAcceptedKeyTypes=+ssh-rsa ec2-user@ip

    Note: the ssh call will accept both .cer and .pem filetypes.
