Hi! I have solved the problem.

The error was not in the magnum or heat, but in the mariaDB which openstack uses.

This made my openstack so unstable and errors like HTTPInternalServerError appeared.

What I did was just changed the mariadb maximum connection in the configuration file and restarted it and all works fine now.

Below is the reference I found on google about how to solve the problem (
