Right, but your VCL is evidently doing something in the form of error handling, since it reacted to the fetch error (which is seen in VCL as response code 503) by redirecting, with response code 302 and a Location header. The redirect goes to "/oops" with obj_status=503, obj_response=Service Unavailable and the request XID in the query string, which sounds like custom error handling. > As for the backend, I'm using Apache 2.2.31 and I have checked the > logs but it seems that everything goes well there and I get status > 200. Sure, your Apache might be getting 200, but it took over 5 seconds to do so, and Varnish didn't wait that long. Look here: ReqEnd c 2005611725 1451213252.184271336 1451213257.219164610 0.000056505 5.034824371 0.000068903 The second-to-last number tells you that Varnish waited just over 5 seconds for the response and gave up, causing: FetchError c http first read error: -1 0 (Success) That's a first byte timeout, which is very likely set to 5 seconds. Always look for FetchError records in cases like this. "http first read error" is very common, it means your backend was too slow. > Maybe I need to enable something in the Apache config? Impossible to say from a distance. It might help to tune your Apache, but it might be something else entirely, such as database fetches in your application that are taking too long.
