Question

I got above error for "ssh -Tvv git@bitbucket.org" Can anyone help to take a look. One note is I don't have local admin to this MacBook, will that be the root cause? Thank. Config file looks like: Host bitbucket.org HostName bitbucket.org user git IgnoreUnknown yes AddKeysToAgent yes IdentityFile ~/.ssh/id_ed25519 Log output is: OpenSSH_8.6p1, LibreSSL 3.3.6 debug1:

From reviewing the log, it seems like the key you're using is getting rejected.

Have you uploaded your public key to your Bitbucket profile settings? You can refer to our SSH troubleshooting KB for some potential solutions, including adding the SSH key to your Bitbucket profile. Please try these suggested resolutions and see if they help resolve the issue.
