github synchronization failed

Question

This is a newly created cooperative organization. I could still upload and update at the beginning, but when I tried to synchronize again at night, it prompted a synchronization failure

Restarting and changing the network are all useless, and Baidu search for gitshell is useless.
Why does GitHub always fail to synchronize suddenly? Is it because of the wall or something else? Is there a more detailed solution?

Answer 1

Maybe the version repository on your github no longer exists or your local ssh key is not passed
