amplify-swift: Amplify.auth: "Channel shutdown due to tls negotiation timeout" error, but only on mobile networks (works ok on wifi)

Describe the bug

I am writing a swiftui app using Amplify Auth/Cognito. I was able to get everything working well (Sign-up/Sign-in/Logout/etc…) until I tested it on a mobile network outside of my usual WIFI.

When on mobile networks I am getting a network error, however not only that my network is fine, also other network operations inside my app are working without any problem.

The error is:

“Channel shutdown due to tls negotiation timeout”

Steps To Reproduce

Steps to reproduce the behavior:
1. Use Amplify Authenticate in a Wifi environment - no problem, all works fine
2. Turn off wifi, open the app in the street while on mobile (5g) network - getting errors
3. One thing to note - I am in France, and I am using the us-east-1 server. However my fiber (and wifi) provider is the same as the one I am using for mobile.

Expected behavior

I expect everything to work as usual agnostic to what type of network I am using.

Maybe there’s a restriction using a US based server from a carrier in Europe?
