Just ran into a bit of a problem.
I did routine updates to my site 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
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 The installation is originally made with Discourse 1.5b in December, but switched to stable branch when it was released in April.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?

There seems to be a flood of errors in nginx/error.log
