[Bug]: Local addons-server Throws 502 On Larger Files

[chrstinalin]

What happened?

In a local environment, uploading any file >5mb will cause a nginx 502 and only fixed with a make down/up. This doesn’t happen on dev — add-ons up to 200mb can be uploaded successfully and anything larger errors as expected.

What did you expect to happen?

Files up to the expected limit (when >5mb) are uploaded successfully and without error.

Is there an existing issue for this?

Note that there are 2 issues here:

• client_max_body_size should be set to 200m or so (letting us upload files that are 199.9 MB, if we account for the rest of the request body)
• the weird proxy thing we do where requests go through addons-frontend should either be fixed or removed completely (while keeping addons-frontend pages working locally)

[diox]

We could also try to fix the proxy in addons-frontend - the error seems to be coming from there. But if it's not an easy fix we should probably stop doing that entirely like suggested above.

• client_max_body_size being too low causes a 413
• Proxy causes a 502
