Firewall drops requests to Stripe Tax Provider

firewall

#1

Hello there.
I have a site which integrate stripe as a payment system.
I’ve integrated own tax provider in my application, but is seem that stripe can’t connect to that endpoint. Only one from 3 requests passed to my server.

Could you suggest how to ensure that the given url is not protected by anything and allow all incoming requests to given URL

especially https://onlinetouch.nl/stripe-credits/taxes

Disabling all the security for given URL helps
