Answer 1

There could be multiple reasons for this, I would probably just check for this first

ssh -vT git@github.com

Analyze the output to see what comes up

Answer 2

May be this problem occurred when you tried accessing your github account using a new system mostly MacOS. To do the authentication that you are accessing the correct server the your OS uses ssh protocol to communicate to the github server. For that the ssh key generated by your OS should be saved in the guthub.

Follow the steps given in official docs of github. The error occur mainly due to the absence of ssh agent key in your github. You need to generate one in your OS and then paste it in the ssh key setting option of github.
