Unable to create/update AD account due to password policy

Hi,

We are trying to create an account in AD. It creates the account in AD but while setting the password it throws below error


Error executing user_password_Set on object CN=91005,OU=Offsite Contractors,OU=US Berwyn,OU=all users,DC=dfctest,DC=local (Error: [System.Reflection.TargetInvocationException] Exception has been thrown by the target of an invocation.
[2226225] Password change for 91005 could not completed. The password does not meet policy requirements.
[System.Reflection.TargetInvocationException] Exception has been thrown by the target of an invocation.
[System.Runtime.InteropServices.COMException] The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)).
Password change for 91005 could not completed. The password does not meet policy requirements.
Exception has been thrown by the target of an invocation.

Even when we are trying to update any user's password, it is throwing this same error. We updated the password policy in One Identity according to AD still didnt work. Please suggest how this can be resolved. Thank you.
