Error 504 on static site generation (WP2Static)

Bắt đầu với đầu ra của WP-CLI wp2static full_workflow và request tới admin-ajax.php, sau đó kiểm tra quá trình xây dựng URL dẫn đến vendor/leonstafford/wp2staticguzzle/src/Handler/CurlFactory.php:210. Tái hiện cấu hình reverse proxy và truy vết lý do URL được tạo chứa customer-care-solution.comhttp; hoàn thành có nghĩa là quá trình tạo tĩnh kết thúc mà không có host bị sai định dạng hoặc lỗi cURL nghiêm trọng.

Hey there.

The static site generation used to work fine but i am not able to run it from a few hours.

I get this error:

504 error code returned from server.
Please check your server's error logs or try increasing your 
max_execution_time limit in PHP if this consistently fails 
after the same duration.
More information of the error may be logged in your browsers console. 

And this is what I get in the console:

Why is http being appended to customer-care-solution.com? And how do I solve this?

My setup:

1. Lokl site with a reverse proxy running on https.
2. Static site accessible on customer-care-solution.com.
3. Modified host files on my computer to point to dynamic WordPress site.
