Since May 2017 the Chrome help forum has been getting more complaints about
'I click the Google search microphone and get a 'No Internet connection' failure.
I clearly have an internet connection, I've reached
google.com and text search works'
We used to see a few of these per month, now I'm seeing several per week.
There is a bug open (issue 717419), but it's not going anywhere because we can't isolate the cause.
It's probably other software (and sometimes malware), that blocks the mic connection and
depends on some Chrome config change, like an auto-update.
How can I advise users how to trace the failure?
Where to look in dev-console?
What to watch in net-internals? etc.
I'm one of the minions that contribute to the help forum.
I have a CM background, but need help on the details of using the tools.
Private email OK.
