HTTP error on iPhone build

Hi Apple Dev community,

I'm facing the following problem:

  • Building a mobile game in Unity, which accesses the database to load the user progress.
  • Accessing the database is a simple Unity Web Request call with a given url string.
  • All calls and everything works well in all setups of the Unity Editor (Android, iOS, PC, ...), on any Android phones / builds and even just in the browser or Postman.
  • However, when I export the project to Xcode to run a test for iOS I receive a HTTP error from the web requests -> HTTP/1.1 400 Bad Request.
  • There is no more information on what exactly fails during the web call.
  • Testing device: iPhone 13 (OS 17.4.1), Xcode version: 15.0, MacBook OS: Ventura 13.6.6.

Did I miss something?

Same for me, did you find solution?
