Can you give us more information about your issue? How did you configure CloudFlare? Did you use any guide to configure it? If so, can you share the link with us? Was your server working before configuring CloudFlare?
I also see the next lines in your
/opt/bitnami/apache2/conf/bitnami/bitnami.conf file which I think are not required. Can you try to remove them and restart Apache?
Redirect permanent / https://www.lovelytrip.store/
Also, did you configure WordPress to use your domain name? You can configure it by running the command below
sudo /opt/bitnami/apps/wordpress/bnconfig --machine_hostname "www.lovelytrip.store"
I also see you are not using the latest version of the bnsupport tool. Can you follow the steps in the link below to download and install the latest version? After that, please run the bnsupport tool again.
Apart from that, we had another thread regarding CloudFlare 524 errors recently. Can you check it in case it helps you to fix your issue?
Hope it helps,
