Log Entry in Fiddler "Network Address changed"

[Pramod Raveendran]

Hello,

I am trying to download few files around (480 no) each file is at least 400 MB to 1 GB of size and i can see so many incomplete downloads (This is for testing purpose).  but when i try manually using my laptop which is connected to corporate network download seems to be working fine. 

i run python script to download files from web through http. 

 installed fiddler in both machine, then i can see frequent error message in "log" tab saying "Network address changed". which i am not seeing in the stable network.

Can anybody suggest me what is exactly this network address change error means? (Attached screenshot below)

Thanks

The message is shown when Windows reports that the Network Address has changed. This would occur, for instance, if Windows switched between Wifi networks because a WiFi network went down and another connection was available.
