Device Portal of Windows 10 Mobile is now available on NuAns NEO but it's not usable. Browsers say “The connection to the server was reset while the page was loading.” This is not a kind of insecure-certificate problem.
My NuAns NEO:
- Windows 10 Mobile, build 10.0.14393.5 (The problem exists since the first 10586 build which come to NuAns NEO as far as I can remember.)
- Firmware rev 1028.020.001.79
I've tested it with the openssl command.

The message lacks server certificate, cipher string and so on. I wonder what situation/configuration causes this. Like the phone vendor forgot to install something?

In contrast, connection to another phone Lumia 1520 succeeds as follows.
