[SailfishDevel] Qt Network: "Network access is disabled" after network change

[Slava Monich]

Unfortunately, no, it's an internal bug. If you would like to be 
notified via email about a potential fix, you could watch qtbase pull 
requests - those are quite rare, it shouldn't be too much of a spam.

Cheers,
-Slava
