Upgraded from git 2.33 to 2.36 and now can't access repos

Question

I upgraded from git 2.33 to 2.36.0.windows.1 today, and suddenly I'm unable to clone or pull from BitBucket. I get the following error:

git@"domain": Permission denied (publickey).

fatal: Could not read from remote repository.

Please make sure you have the correct access rights

and the repository exists

I have found several solutions online (including these forums) and no luck so far. I've recreated SSH keys, made sure they are in my ssh-add/uploaded to BitBucket, etc. Still, no luck. It worked fine immediately before I did the git upgrade.

Has anyone experienced this with the upgrade to 2.36 or have other suggestions on how to get this to work?

The problem is with ssh keys.

Git 2.33 and above, rsa keys are disabled by default.

You need to use ed25519. You need to generate ssh key usinng

ssh-keygen -t ed25519

It will solve the problem

I have experienced this after upgrading to Git 2.36.0 and using Bitbucket 7.17.1.  I was not able to resolve the issue but, upgrading Bitbucket to 7.21.2 fixed it.
