WKWebview page redirect blocked by security rules

We are loading a web page on wkwebview, the page redirects and loads another page but, lately we are seeing the page is blocked by security rules. (PFA)

The same code works fine in PROD environment. it is a third party provider claims we are redirecting twice but, we are not doing any reduction on our own but, I do see more than one call in Charles proxy.

we are using navigation delegates to check for response and see 403 response as seen in the report.

I did enable Allow Arbitrary Loads in ATS but, still same result. please advise
