git@bitbucket.org: Permission denied (publickey) in windows

[Yunus Burhani]

It used to work and all of a sudden stop working. I have changed my keys couple of times as well but nothing is working. I have created a config file as well.

I ran this command

ssh -t -vvv git@bitbucket.org

here is the dump from it

G'day, @Yunus Burhani 

Based on the debug log you've shared, It seems that SSH is unable to locate the private key on your local machine:

debug1: Reading configuration data C:\\Users\\yburhani/.ssh/config
debug1: C:\\Users\\yburhani/.ssh/config line 1: Applying options for bitbucket.org
debug3: Failed to open file:C:/ProgramData/ssh/ssh_config error:2
debug2: resolving "bitbucket.org" port 22
debug2: ssh_connect_direct
debug1: Connecting to bitbucket.org [104.192.141.1] port 22.
debug1: Connection established.
debug1: identity file C:\\Users\\yburhani/.ssh/id_ed25519 type 3
debug3: Failed to open file:C:/Users/yburhani/.ssh/id_ed25519-cert error:2
debug3: Failed to open file:C:/Users/yburhani/.ssh/id_ed25519-cert.pub error:2

If the SSH key does exist, please review your SSH config again and ensure that it's pointing to the correct key:

Host bitbucket.org
 AddKeysToAgent yes
 IdentityFile C:\\Users\\yburhani/.ssh/{key-name}

The above example assumes that the ssh key is generated at "C:\\Users\\yburhani/.ssh/". If it's in a different location, please update them.

Let me know how it goes.

Syahrul

I have this file in the correct place

debug1: identity file C:\\Users\\yburhani/.ssh/id_ed25519

I do not have these files as it should not be using certs

debug3: Failed to open file:C:/Users/yburhani/.ssh/id_ed25519-cert error:2
debug3: Failed to open file:C:/Users/yburhani/.ssh/id_ed25519-cert.pub error:2

I changed my config file to give full path

 IdentityFile C:\\Users\\yburhani/.ssh/id_ed25519

It used to be

 IdentityFile ~/.ssh/id_ed25519 

Still did not work

Hi @Yunus Burhani 

Could you please confirm if the SSH key generated earlier is the one you are using and if the public key has been added to your Bitbucket account? Ensuring that all steps outlined in our guide have been properly followed is important. Please see below for the guide:

https://support.atlassian.com/bitbucket-cloud/docs/set-up-personal-ssh-keys-on-windows/

[Yunus Burhani]

I figured it out. My git was updated recently and lost the connection to ssh.

Thanks for all your help.
