Hi,
I'm struggling with a 502.3 Error Code 2147954552 problem. I already analyze the Bad request routing logs. No info there, only Error code mentioned at the beggining. I stuck. I can only say when the cookie for the website is on client side then I have this problem. When the user will remove the cookie then everything is routed properly. I will be apriciate for any help.

    After spending many days and nights, we found root cause of this issue as spaces mentioned inside text of one of the HTTP Response Header value. Reference to screenshot below is the correct and incorrect value:

    Incorrect Value: Header always set X-Content-Type-Options

    Correct Value: X-Content-Type-Options

    Hence do not provide any space between any value of response header.

    HTTP Response Headers can be found in feature view of web application or at IIS Server Name level.User's image

    Thank you very much for trying to help. Unfortunatelly it will take for me some time to check if this works. It's almost two years since topic starts, but I never found an answer so it will be interesting to test what you found.
