playbook fails when run through Ansible tower

It clearly states the reason. Try updating the password in credentials. Maybe a typo is causing this.

I checked, password if I pass , is correct, re-confirmed by another user. (As you are right its easy to make this mistake even after all care fulness).

Moreover it should not have been required, as I use certificate, and is configured.

Instead of using become true in playbook, try using “enable privilege escalation” from the job template UI.

Hope this helps

I already tried this. Enabling and disabling. In either case it didn’t work.
