Images from subdomain not loading in Apple devices

Job ID: 34134943

Budget: ₹100 – ₹400 INR

I have a website developed in laravel. The website loads some images from the website itself (oxygentimes.com) and some from subdomain called admin.oxygentimes.com. All the subdomain pictures are not visible on Apple devices like iPhone.

According to a StackOverflow answer, it seems like some issue with SSL, but I can't figure out how to fix it.

Here's the StackOverflow link: https://stackoverflow.com/questions/61666323/website-images-not-loading-from-other-server-on-apple-devices-safari

Screenshots from iPhone attached. Looking for hourly bidders. Please bid only if you are 100% sure about how to fix this.
