God, No!!
"Local Host Debugging" is one of the newest features in HTTP Tools. And we thought that when this feature was launched along with the update in version 4.1.8, this feature was still fine. Apparently, in the latest version, we have upgraded the Android SDK version to target the latest Android version. And this causes problems with the "Local Host Debugging" feature because the security permissions for the application to access a domain have been revoked.
We will fix this feature soon in the next version of HTTP Tools. I apologize for this inconvenience.
