503 Error

Here’s the error log file: https://www.dropbox.com/s/0tty31sndajuxhi/php-fpm-error.log?dl=0

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)

My host (Pantheon) doesn’t allow me to play with Varnish settings.

Backend/Server settings aren’t my specialty. Is there a different log file that might offer some insight?

Hey @doulos12, have you been able to raise this with your host? If so, what was their response?

Does turning Varnish off solve the problem?

Thanks,
Igor

Can’t turn off Varnish, but with the host in question, Pantheon, it turns out their caching plugin was causing problems. I turned that off, and their support crew submitted a bug report to their code monkeys. All good for now, waiting on them to release a plugin update. Thanks for following up.

Hey @doulos12, thanks for letting us know. Hope they sort it out asap.

All the best,
Igor
