Discourse was working great for a few months, then I wake up to find the page won’t load. Not sure if something changed in my system’s config or what. I tried `sudo ./launcher rebuild app` that didn’t seem to help. Then I tried `sudo ./discourse-setup` again, that got the site to at least load.
The problem is its loading a blank white page. When I check the inspector it returns pretty much all js files as 502 gateway errors. If I load the site on http instead of https, the errors are all 404 instead of 502.
I did a `sudo ./laucher enter app` and verified all the files exist - and they do, so I am at a complete loss. I was thinking perhaps an error in my nginx front end configuration, but I see nothing out of the ordinary.
Is there something I have forgotten or am I doing something incorrectly in my config or what could be going on?

Are you out of disk space?
Try
```
./discourse-doctor
```

100% not out of space:
discourse doctor reports:
```
========================================
Discourse 2.2.0.beta8
Discourse version at domain.name: Discourse 2.2.0.beta8
Discourse version at localhost: NOT FOUND
==================== DNS PROBLEM ====================
This server reports NOT FOUND, but domain.name reports Discourse 2.2.0.beta8 .
This suggests that you have a DNS problem or that an intermediate proxy is to blame.
If you are using Cloudflare, or a CDN, it may be improperly configured.
```
This is why I was thinking some sort of issue with the nginx config. I am not using cloudflare or any CDN, which only leave the nginx front end config.
All DNS checking tools I haev tried say my DNS config is fine.

Ah. No. Discourse-doctor doesn’t know about your reverse proxy so that’s a red herring. Sorry. That’s no help.
Is the server overloaded? Recent update causes images to be reprocessed.

Not as far as I can see, load averages are low, bandwidth usage is low, memory usage is low, nginx usage is low - nothing unusual from what I can see.

Consider this problem sorted.
Apparently the control panel I use to manage my server has a bunch of different nginx setups, and I had somehow managed to switching it from a default proxy nginx configuration to a caching nginx configuration.
The minute I switched it back to a default proxy config, everything started working again. Only 3 days wasted trying to sort this and in the end it was completely unrelated to the server{} directives of nginx.
