Service does not work over HTTPS when using custom port, but works with HTTP

Have two services running in Lightsail node instance, one on port 8080 and second on 8081. I've made mappings to access service 1 from :80 and service 2 from :3080. In case of HTTPs it should map :443 and :3443 respectively. Everything works fine for HTTP, but adding HTTPS cannot access :3443 over network - getting timeout.

Can access over HTTP the <static_ip>:80 and <static_ip>:3080 without any issues. Over HTTPS however, <domain or distribution address>:3443 times out. But <domain or distribution address>:80 is working fine.

TL;DR my custom port is not working over https. Firewall rule for 3080 and 3443 is added.

Here is config changes I've made to bitnami apache configs:

Pardon my overall ignorance & thanks for any help debugging
