Issue
Yesterday I updated github's fingerprint, but after that I cannot use ssh to connect to github.com anymore.
I've tried to regenerate key and added it to github. But it still doesn't work.

[email protected]'s password:
I have id_ed25519
and id_ed25519.pub
in my .ssh folder, and I'm sure I've added it to github's ssh keys. Plz any suggestions?
Solution
I encountered the same problem today...
In my case, on the first time that I tried to push to GitHub today, it warned me with "REMOTE HOST IDENTIFICATION HAS CHANGED".
Thus I updated GitHub fingerprint, and on the second push it prompted me to input "[email protected]'s password"
After several trail, I found I can't even connect to GitHub.com in web browser without using proxy, I don't know if it is the same with you.
Then I manually set GitHub's IP address in hosts... and everything goes back to normal...
