I’ve just created my brand new WordPress website via Bitnami WordPress with NGINX on Google cloud. After that, I’ve installed the Jevelin theme and import demo ‘Single Product’ theme.

Activated all plugins come with the Jevelin and without additional unfamiliar plugin downloaded, I’ve found my site (http://35.240.237.233/) cannot load anything. It stuck on the loading screen. Moreover, I cannot configure anything on the Jevelin >> Templates menu since it shows only WPBackery’s white loading screen.

I have no idea what causes this?

FYI
<div>
<div>WordPress version: 5.5
Jevelin version: 4.7</div>
PHP Version: 7.4.7
<div>Server info: nginx/1.18.0</div>
Thank you in advance.
