Bug ID: 40645
           Summary: Rocket league: ingame internet connectivity lost
           Product: Wine
           Version: 1.9.9
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wininet
          Assignee: [e-mail]

      Distribution: ---

In wine 1.9.9, Rocket League (Steam version) is working but only in solo, the
game is saying it cannot connect to internet.
By downgrading to wine 1.9.8, the game can go online and everything is working
flawlessly.

I applied the regression testing procedure and found that the faulty commit is:
[221590213ea12375cb2549afd774855dcc6c46e6] wininet: Handle async mode in
HTTPREQ_ReadFile.

Note: done on ArchLinux x64 with a 32bit wineprefix. Package lib32-gnutls
needed to have network access ingame with wine 1.9.8
