Blocked:Mixed content issue in live server

I am using jQuery(ajax) for some actions, like fetching sub_categories when I select a category this time. But on the live server, when I change the category, it throws an error (blocked:mixed-content). I got the issue that this request sends HTTPS to HTTP, which is why it shows this error. But I don't know why it's requested in HTTP. My domain has SSL. I fetch the same issue when I upload images via livewire.Please help me laravel version -11.15.0 I am using a subdomain and a VPS with Cpanel
