Let's Encrypt Bitnami AWS Lightsail issue - automatic renewal

I'm running 2 instances on AWS Lightsail (Bitnami Wordpress installation) that have both recently failed in their Bitnami HTTPS Configuration Tool (automatic renewal).

I've attempted to problem solve but I've been unable to do so.

I need somebody well versed in Bitnami Wordpress installation on AWS Lightsail. This prject should take 30 minutes to complete
