Proxy buffer size needs to be increased

[lewtds]

I got this in my Nginx log and a 502 response:

2020/01/23 10:02:50 [error] 8496#8496: *274 upstream sent too big header while reading response header from upstream, client: 127.0.0.1, server: <REDACTED>, request: "GET /api/322/config/wifi/ HTTP/1.1", upstream: "https://104.26.5.98:443/api/322/config/wifi/", host: "127.0.0.1"

I increased the buffer size according to this guide and it works.

Hi, Thanks for reporting, what is exactly the value that you have set up? If you don't mind adding it to the nginx.tmpl and submitting a PR, that would be awesome! Loric
