I'm running my build in a FreeBSD jail which does not have a loopback address, localhost host resolves to 192.168.200.44.
On upgrading to 1.12 or 2.0 I get the error below:

$ ./gradlew clean
:buildSrc:clean
:buildSrc:compileJava UP-TO-DATE
:buildSrc:compileGroovy
Cannot accept connection from remote address /192.168.200.44.
:buildSrc:compileGroovy FAILED

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':compileGroovy'.
  > Unable to connect to the child process 'Gradle Compiler Daemon 1'.
  It is likely that the child process have crashed - please find the stack trace in the build log.
  This exception might occur when the build machine is extremely loaded.
  The connection attempt hit a timeout after 120.0 seconds (last known process state: STARTED, running: true).

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED
