Http/2 does not work on Wordpress site on Amazon Lightsail

Hello,

I have a wordpress bitnami website on Amazon Lightsail. I have followed all instructions to enable http/2 but it seems it does not get activated. When I run apachectl -M on the server, it returns http2_module (shared), http_module(static), proxy_http_module (shared). But testing http2 on Google dev tools or any other http/2 testing site, says "HTTP/2 protocol is not supported" and "ALPN extension is not supported." The certificate for the site is created using Lets Encrypt bncert that is included with Bitnami on Lightsail.

I have followed the steps for enabling http2 in apache and virtual host, but still does not work.

Any advice would be appreciated.
