Hello @Mansi Swami ,

Welcome to Atlassian Community! 

This error is usually returned when the SSH key being offered by your machine either does not have sufficient permissions to execute the action or was not properly added to your bitbucket account.

In this case, I would suggest following the instructions on the page Troubleshoot SSH issues for Bitbucket Cloud.

If after following those instructions you are still facing the error, I'd like you to share here the output of the following command: 

ssh -Tvvv git@bitbucket.org

This will provide verbose logs of the SSH authentication and a possible indication of what is the issue.

Let me know if you have any questions.

Thank you, @Mansi Swami !

Kind regards,

Patrik S
