    The solution to this issue is quite simple. It occurs often on Apache servers and it’s all due to the KeepAlive directive.

    Edit /etc/apache2/apache2.conf

    KeepAlive On Change to KeepAlive Off

    Open your Varnish configuration file (mine was in /etc/varnish/user.vcl) and add these lines:

    backend default { .host = "";   .port = "8888"; .connect_timeout = 1s; # Wait a maximum of 1s for backend connection (Apache, Nginx, etc...) .first_byte_timeout = 5s; # Wait a maximum of 5s for the first byte to come from your backend .between_bytes_timeout = 2s; # Wait a maximum of 2s between each bytes sent }
