As our VM is not exposed to the outside of the UA network, we can't generate a free SSL certificate with Let's Encrypt (as it can not validate that our server exists). As the solution is a paid certificate, while the project is in development we are going to use a certificate signed by a CA created by us.
Followed the tutorial on https://www.ibm.com/docs/en/runbook-automation?topic=deployment-generate-install-signed-rba-server-certificate
As we created a custom CA it is not expected for browsers to trust it. To bypass this problem, just add the root CA certificate as a trusted CA on your browser settings.
It's location is <frontend-backend-repo>/ssl/internalca/rootCACert.pem.
