I’ve created a new SSH key on ~/.ssh/id_rsa and I added the public key (~/.ssh/id_rsa.pub) on my Azure account but when I try to perform any action on git it returns the following error message:

Command to create SSH Key:

ssh-keygen -t rsa -C "[email protected]"

Also, when I try to test ssh connection with Azure git, it returns the same error message.

ssh -T [email protected]

input_userauth_error: bad message during authentication: type 7

Here’s the output message for the following command

ssh -vT [email protected]

Same problem happens if I try to connect to my Github via SSH. I believe it is an SSH issue or config but I don’t have the knowledge to troubleshoot it. Still reading about to figure this out.

Any help to solve this SSH problem?

I already tried to create others SSH keys and added them into my Azure account.
Important to note that one month ago was working properly and for some reason now it’s not.
