Comment (by Hilaus):

 More information:

 In my case, It’s with POST requests only, and only with Magento (I suppose
 because Magento uses different VCL from others that POST works fine).

 With 4.0.3 works perfectly, the problem is only with 4.1. The same system
 and configuration with 4.0.3 works fine. I update varnish to 4.1, and POST
 requests starts to fails (it waits 30s and send a timeout).

 A example when that happens (in this case, the host doesn't have SSL. But
 with SSL happens the same):
