Uploading mods via nginx proxy is giving 500 error

[itzg]

I suspect it's due to the file upload size limit.

From nginx logs

Note

It's file upload size related (which makes sense) since an 8 KB mod worked fine. A 200 KB did not work.

I'll revisit the proxy image if/when this PR is resolved https://github.com/smashwilson/lets-nginx/pull/7
