[Interest] OSX: Losing internet and regaining it does not allow XMLHttpRequest to work

[Jason H]

I have an app (mobile, but develop mostly on OSX (God I love Qt!)) and I'm trying various failure modes. 
I login in the app,
Disable wifi,
Attempt a request, it fails
Re-enable wifi,
Attempt request.

It seems that once a XMLHttpRequest fails, even  after if I reenable wifi, Qt will always immediately fail the request. 5.5.1, 5.6 beta. has anyone else seen this?
