[tbb-bugs] Odd behavior

[greenish_cloud]

Hi

Thanks for all the great work on Tor.

On 8-12-2021; Using my phone as a hot spot, it refused connection standard Tor Connection using latest Tails 4.21, with Tor latest Tor 10.5.4. Whatever came with latest Tails that I downloaded yesterday. It automatically kicked over to using the first internal bridge. and logged on. Looks like the phone ISP is blocking standard Tor. How did it know.

Phone is Google Pixel 4A with 5G, Android 11, updated Android. My phone is connected with with WalMart Straight Talk, actually using AT&T Sim. Although the connection is shown as TracFone. The APN is TracFone with reseller underneath. I have unlimited data, which comes with 5 GB HotSpot.

This morning, I just tried to use Windows 10; Start Tor 10.5.4. Windows 10 says Windows Defender blocked connection with bridge obfs4, it allowed third internal bridge "snowflake"

Tor is being blocked. I am surprised in that AT&T blocks a standard, non-proxied, non-bridged connection using Tor inside Tails.

This looks like the phone hot spot can detect Tails. Which might be concerning to some.

Best Wishes
