This is a customer setup, and we are unable to reproduce the issue locally in our lab. The customer is experiencing unusual behavior they report that VPN performance is fine when connecting to a nearby VPN server, but it slows down when connecting to a server in a distant location. We have asked them to check their network and infrastructure on their end, as we believe this may not be a VPN issue, they are looking into it. For the first issue where the VPN fails, our investigation suggests that the socket enters a bad state once the device is locked and extension goes to sleep. It is neither timing out nor sending data, which indicates the socket enters a bad state and the resource is not accessible. Note: Both issues are not reproducible on iOS 18.
