      We've discovered the issue on different addresses that work perfectly in the browser (Firefox and Chrome) but fail on QT 5.12.0

      We've been able to verify that QT 5.5.1 was not affected.

       

      Example addresses:

      https://hazards.fema.gov/gis/nfhl/rest/services/KMZ/KMZ/MapServer?f=json

      https://hazards.fema.gov/gis/nfhl/services/public/NFHLWMS/MapServer/WMSServer?request=GetCapabilities&service=WMS

       

      The error returned is "Connection closed"

       

      Please find attached a failing test case.
