    Description

      Issue experienced during a rollout from Google's GLB (Global Load Balancer) where QNetworkRequests were immediately dropped with GOAWAY and log message indicating  "Server is unable to maintain the header compression context for the connection".

      This is a client error resulting in the server side dropping the connection immediately as per https://httpwg.org/specs/rfc7540.html#HeaderBlock. If the server side had a failure in the header, Qt would emit a critical message "HPACK decompression failed"
