Ansible Tower vault issues

[nbmp...@gmail.com]

Hi there,

I've setup Ansible Tower and imported a ansible project from a Git repository.

Credentials for localhost and vault (prompt) have been added.

The playbook normally runs like this: 

ansible-playbook Playbooks/vsphere-vm-provisioning/deploy-tmc.yml --ask-vault-pas

The output in Tower after entering the vault pass:

Enter passphrase for /tmp/awx_5_OU8MlQ/credential_3: 

Bad passphrase, try again for /tmp/awx_5_OU8MlQ/credential_3

My roles only use encrypted variables in main.yml in the vars folder.

Anybody know what is wrong? 

Thanks in advance.
