I have the website on the hosting (e.g. https://example.com), and I have a page on this domain, that makes request to the backend, located on another domain (e.g. https://example-2.com located on AWS EC2).Both domains have SSL certificates (I guess, both from Let's Encrypt).For some reason I am getting Bad Request Error.
On frontend I get net::ERR_SSL_PROTOCOL_ERROR.
On backend I see the following:

I understand that the issue might be in encryption, but I have no clue how to tackle this.I am using CORS for Flask.
I tried to make requests https -> http and https -> https, but the result is the same.
They have Phusion Passenger on the hosting, and i have Nginx on my EC2.
