Just ran into a bit of a problem. I did routine updates to my site [Tappara.co](http://tappara.co): - 1.6.2 → 1.6.4 via _git pull_ and ./launcher rebuild app - It went cleanly. - Installed a few updates available to Ubuntu 16.04 server - Rebooted Now the site refuses to come back online. Now this stuff goes beyond my linux sysadmin skillz. From what I can see, Docker is running and so does the **app**. I see relevant processes (ruby etc) starting, but basically idling. The site is reporting a 521 error. Tried re-rebuild a couple of times, but no luck. The installation is originally made with Discourse 1.5b in December, but switched to stable branch when it was released in April. I would **guess** that http requests are not correctly routed, but I have not touched any settings or parameters of that field. This is basically a default installation. I do not have Let’s Encrypt or other certificate enabled. - Anyone seen similar recently? - Newbie friendly tips on how to start diagnosing and fixing? There seems to be a flood of errors in nginx/error.log ``` 2016/09/28 12:32:09 [emerg] 977#977: invalid number of arguments in "set_real_ip_from" directi$ ``` --- _[View the full topic](https://meta.discourse.org/t/urgent-site-down-after-upgrade-to-1-6-4-due-to-cloudflare-template/50789)._
