Cause If I am using ssh, public key between servergit probably does not match or not connected. $ git push origin main git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. ... Solution Create new ssh key on github. #Get the public key from server. $ vi ~/.ssh/id_rsa.pub >>> ssh-rsa AAAAB3NzaC1yc2EAA ... And then issue the key in github.
