I know its an old post, but thought it’d be helpful to let everyone know how I fixed the same issue.

There was nothing wrong with the nginx.conf. In my case I had configured an unsupported password for “rabbitmq\_password” in the inventory file before running setup. The password can have only alpha-numeric characters and cannot have any special characters.

Once correct password is given and re-run setup everything works fine.
