I would imagine there is some kind of redirect that is setup somewhere within the site that’s causing this.
You may want to check any redirection plugins and possibly temporarily disable them one-by-one to see if one is causing this issue.
I’m seeing the following redirect when curling a page:
curl -sIL "https://banghenhomduc.com.vn/gioi-thieu-ve-nhom-duc-faco/"
