If the connection failed, like it seems to have done here, you do not end
up in VCL fetch. Note how varnish doesn't receive any headers from the web
server (no RxHeader for the second backend).

Varnish is unable to connect properly to your second server and that's
what's causing problems.

Varnishstat will probably reveal backend failures.
