I’m having this happen on Mac but only with the public release. An older version is able to build without an error but the latest release gets a build error #11 as well and the console log displays a XMLRPC request failed with a Timeout.
I’m unaware of any systemic build errors with the latest public build (2731) we’ve tested it quite well. You might try a different internet connection (if you have a laptop, try a coffee shop).
Its definitely not a network issue having tried it from several different networks now. Â I am on 2731 and get either error #11 when building for android, or unexpected empty response from build server when building for ios. Â Both are being done from osx.
FYI I am able to build from the same machine and same network with build 2693 however I cannot build a distribution release since it says I am building with a betaÂ
Update: I am able to build an android version on Windows 7 from the same network as my macbook but with a different login account.
Further update: Â turning off Enable Analytics and Monetization (the fuse integration) allows me to build.
We found the server doing the builds had a slow connection causing a timeout in the Simulator when Monetization was enabled. The server connection issue seems to come and go. We have disabled the timeout in the latest daily build (2742) so you should try that if you are still experiencing problems.
I’m still having this issue unfortunately, on about 80% of my build attempts. As far as I can tell the issue is resolved if I uncheck the “enable analytics and monetization” box.Â
I’ve tried 2742 and 2750 and still get an error every time I build with monetization enabled.  I’ve had to go ahead and release a version without fuse in it since I can’t get a build with it enabled.
This turned out to be a subtle issue in the Simulator’s networking layer which caused larger device builds to sometimes timeout.  It should be fixed in Daily Builds 2754 and after.
