Cannot start Django app deployed on Apache

I have deployed my Django project on AWS Lightsail using Apache and mod_wsgi for prod deployment. Created SSL certificates - they are ok.
Turned DEBUG off in and followed Bitnami and Django prod deployment recommendations.
Updated Apache https-vhost config.
When I restart Apache server my app should start - but it doesn’t.
I guess something is wrong with Apache config, but I cannot figure what.
Please help!
