Access Denied, you do not have permission to access <insert site> on this server.
Ever since updating to iOS 17.1.2, one website and it's associated app will not allow me to log in giving me the titular denial and a reference number. This isn't affecting any other site/app/service I use. I have thrown everything I can at it. Soft reset, cache clear, switching to data connection, resetting internet connection, all to no avail. I have no problems signing in on my desktops on the same connection running software that is years out of date. What is this, and why hasn't it been addressed? To me it seems obvious the iOS update is responsible for this. Nothing else is malfunctioning. Is this something Apple will have to address in another iOS patch, or something the service/app developer will need to address? For the record, there is no VPN in use, no content blockers, or restrictions, and all ports are open for said service on my router. I need an explaination. This is unacceptable. Thank you.
