SSL Certificate detected but Chrome Extension says it’s invalid

Hello,

I have purchased and installed the latest version of WooCommerce Photo Reviews, but I face the following issue when I try to import reviews from Amazon using the Chrome extension:

“Your site must have a valid SSL Certificate and have WooCommerce Photo Reviews (v1.1.4.8 or later) installed and active.”

I have already verified the following:

I updated the plugin to the latest version.
I entered and activated the Auto Update Key.
The plugin is active.
My website is running over HTTPS with a valid SSL certificate.
The Chrome extension is enabled.
The correct domain and password has been added in the extension settings.

Could you please help me identify what could be causing this issue?

Thank you.
