503 Error

Hey @doulos12, unfortunately, all that I can see from the logs is that the page is loading slowly.

Temporary solution would be to increase Varnish timeouts.

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

backend default {
  .host = "127.0.0.1";
  .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
}

The most important settings here is the first_byte_timeout. So go ahead and play with those settings until it starts working. (I’d recommend setting 8-10s timeout, since logs say that it loads in about 6.5 seconds)
