to fire the following command: varnishlog Once the command is running, load up a page from your website on your browser and look for any errors. This literally means looking error 503 service unavailable service unavailable guru meditation varnish cache server for the word "error". Pretty sweet, huh! Now let's get on to our first solution. Solution 1 - General check Most of the times, Varnish 503 means Varnish cannot connect with your backend (Apache, Nginx, etc…). So you should start from there. The first thing is to make sure your backend is correctly configured. That means making sure your Apache/Nginx/whatever is running properly before installing http error 503 the service is unavailable Varnish. If you've installed Varnish on a properly running instance, then you might just check that installing Varnish hasn't done anything funny to your Apache configurations. Here's what you can do: Open your Varnish configuration file. Mine was in /etc/varnish/user.vcl backend default { .host = "127.0.0.1"; .port = "8888"; .connect_timeout = 1s; } We can see that Varnish is trying to connect to port 8888 on the same machine. But is our backend responding correctly there? Let's try this (make sure you run this on your server, this port will probably be blocked to the outside world): wget http://www.your-site.com:8888 This will create an HTML file with the output in your current directory. Open the file and see if it matches your website's homepage. If it does not, then you need to configure your server. This is beyond the scope of this post, I'll advise you to check the Linode Library for resources. Solution 2 - Increase timeouts A frequent cause of Varnish 503 errors is timeouts between Varnish and your backend. This is quite easy to solve. Open your Varnish confi

I had similar problem because of unhealty backend. BR Wed, 2011-08-03 02:12 david Hello, This line from varnishlog really stands out as the problem: 12 FetchError c straight read_error: 0It sounds like your web server may be providing an invalid Content-Length header for the content it is sending (or not providing one at all when it should be). I can't be entirely sure with the info you provided, but this sounds like the problem. Can you try testing with different files? Different names, sizes, etc. Are you able to modify your web app to make sure all necessary headers are being set? Regards,-david

Best guess is nginx is working fine, your back end application can't be communicated with for some reason - configuration or firewall. From the server try to curl the application it's proxing.
