github - git always reports an error when pushing the local library to the remote library. What should I do?

Question

Does anyone know what's going on?
You can make sure that the ssh key has been added to the remote library. There is no problem in adding the remote library in the previous step, but there is a problem when pushing content to the remote library

Answer 1

I have encountered it before, you can wait and try again! Or test whether the connection is normal$ ssh -T git@github.com
