ESP32 connection to husarnet doesnt work on phone hotspots, only wifi routers
Hello all,
I am using an ESP32 to connect to the husarnet website to make a connection between two devices across the internet.
When I set it to connect to my home wifi network, it connects with no issues, and I can see my device as active on the husarnet website.
When I set it to connect to my phone hotspot, it makes a connection(ie gets IP address), but the requests to the husarnet site go unanswered, so it never pairs correctly. When I connect other devices(ie tablet web browser) to the hotspot I have full internet connection.
Is there something about an phone hotspot that would block the connection? I tried it on both iphone and android. Is it a lack of port forwarding or IPv6 limitation?
For the project I’m making I really need to be able to have someone set up an SSID and password to a pre-determined value(ie the one I program in), and the easiest way to do that is with a phone hotspot.
Samples of the debug output are listed below:
