Server rejected connection

Question

I am getting the message Server rejected connection. $ ssh -Tv git@bitbucket.org OpenSSH_7.7p1, OpenSSL 1.0.2p 14 Aug 2018 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to bitbucket.org [18.205.93.1] port 22. debug1: Connection established. debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_rsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_ed25519-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_xmss type -1 debug1: key_load_public: No such file or directory debug1: identity file /c/Users/dkerrisk/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_7.7 debug1: Remote protocol version 2.0, remote software version conker_1.1.77-453a2b4 app-155 debug1: no match: conker_1.1.77-453a2b4 app-155 debug1: Authenticating to bitbucket.org:22 as 'git' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256@libssh.org debug1: kex: host key algorithm: ssh-rsa debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ssh-rsa SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A debug1: Host 'bitbucket.org' is known and matches the RSA host key. debug1: Found key in /c/Users/dkerrisk/.ssh/known_hosts:1 debug1: rekey after 134217728 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: rekey after 134217728 blocks debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/dkerrisk/.ssh/id_rsa debug1: Trying private key: /c/Users/dkerrisk/.ssh/id_dsa debug1: Trying private key: /c/Users/dkerrisk/.ssh/id_ecdsa debug1: Trying private key: /c/Users/dkerrisk/.ssh/id_ed25519 debug1: Trying private key: /c/Users/dkerrisk/.ssh/id_xmss debug1: No more authentication methods to try. git@bitbucket.org: Permission denied (publickey). $ ssh-add -L Could not open a connection to your authentication agent. In sourcetree my ssh keys are defined in: C:\Users\dkerrisk\Documents\Projects\sshkey.txt This just started happening this morning, and has been working for months. How can I fix this, and what caused this to happen. Dennis

Hello Dennis,

Thank you for reporting your steps taken along with the output from an attempted connection. From the response you sent I do see the following: Permission denied (publickey). This points to an issue with your SSH key being used to communicate with Bitbucket. You did mention that this has worked without issue until recently. With this said, I would proceed with creating a new SSH key to be used. The steps to complete this may be found at Set up an SSH key.

If you run into issues creating the key or are still having issues after creating a new key please reach back out and let us know.

Regards,
