I just hosted my ASP.NET Core MVC website on IONOS, and when I try to checkout on the cart and waiting for the stripe page to load, I have this message after 1 min of charging :
The page you are looking for is temporarily unavailable. Please try again later. 9eeb7ddf3b19029e2f372010a516dd7d d53615e798fecc1eb02f23aa4cd8f9c7 917ff949b7dc5126f56ec485b2a3c885
The checkout works fine locally.
I tried with a simplified exemple of checkout, but the same error. I think it's the ionos firewall who are blocking stripe API. But i don't have access to this settings, to try to give permission to stripe API. Maybe it's something else, if someone can help figure this out. Thanks
