I re-tested with Qt 5.4.0 (from the ppa) and a custom build of unity-
scopes-api (with switch-to-netcpp branch reverted) and I couldn't
reproduce the networking issues of smartscopesproxy anymore. It looks
like Qt 5.4.0 did fix that particular instance of the qt networking
issue for us.
I cannot c
If it's something that is not NM backend specific but Qt networking in
general, it would be an useful data point if Qt 5.4.0 works similarly or
not, see https://wiki.ubuntu.com/Touch/QtTesting. If it would work
better, we'd know there's something between 5.3 and 5.4 fixing the
issue, in qtbase.

Unfortunately the patched version of Qt from landing-001 didn't help
with our issue with smartscopesproxy (I've tested on an older image #73
on mako; it's important to test on an old image because we've recently
switched to netcpp in smartscopesproxy to avoid these networking
issues).

and rtm:

( 5.3.0+dfsg-2ubuntu11~rtm )
to see if Lorn's patch fixes the issue or not. The patch needed small
rebasing to apply cleanly.

Hi Lorn, re your question from comment #2 (sorry it took so long, I had
to revert to some older phone image to verify that): restarting network
manager service doesn't help. Also, when the problem happens, other apps
(such as browser) work fine, so it's rather an issue with the state of
Qt network

Patch attached that fixes wonky configuration state and also fixes isOnline for

Briefly looked into this, and something odd is going on in the
networkmanager QtBearer backend.
The wifi connection is first reported in the Defined state, and then gets
Undefined for some reason when it should be updated to Active state.
Need to dig further.

Could you try to restart NetworkManager? Does that have the same effect
as restarting smartscopeproxy?

Bug #1409995 affected our smartscopesproxy service, which starts with
user session (keeps running in the background) and handles network
requests by creating QNetworkAccessManager instance with every new
request. So, in theory, since QNAM was re-created for every request, it
should not be affected
