Circle CI container unable to checkout code from github

My team is trying to deploy our code to a server using CircleCI. Seems that circle ci docker container suddenly is unable to clone code. We haven’t done any changes on our permissions. Please help!

Using SSH Config Dir ‘/root/.ssh’
git version 2.20.1
Cloning git repository
Cloning into ‘.’…
Warning: Permanently added the ECDSA host key for IP address ‘’ to the list of known hosts.
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

exit status 128
CircleCI received exit code 128

:wave: Hi @karvex, welcome to the CircleCI community!

Closing the loop here, after replying to the Support ticket you opened regarding this issue, which can be caused by the deploy SSH key (present in the project settings) having been revoked.

In cases like this one, the first thing you might want to try is generate a new key:

  1. Delete the current deploy key from the project settings by clicking the “X” next to the related key
  2. Click the “Add Deploy Key” button to generate a new deploy key for the project
