Unable to push or pull or clone gitlab repo

Hello Team,

   When we try to clone, push or pull the git repo we are getting below error.

Cloning into ''... WARNING: Your password has expired. Password change required but no TTY available. fatal: Could not read from remote repository.

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

Our gitlab version : Gitlab Community edition 9.2.5

Security team changed password policy on server level to set to 15 character length. After that we are getting this error.

We saw some link where they mentioned to delete git password with command " sudo passwd -d git and update /bin/nologin for git user bash.

We tested it but it didn't work. Then we deleted only password for git user id without changing git bash and it allowed us to push or pull data.

Please let me know do we need to reset password for git user id? if we reset anywhere we need to update in gitlab applicaiton configuration? Any effect if we delete git user id password? Till now it is working fine after deleting git user password. Still we need clarification on this.

Thanks, Prashanthi.
