Plugins don't work after setup, 405 Not Allowed

[kylezs]

Once I get subscan working with my local chain for the basic queries e.g. "block: 2" on the subscan homepage, plugins don't work.

If I click Plugins -> { any option } they all fail, here are the request headers:

POST /api/scan/blocks HTTP/1.1
Host: 127.0.0.1:3000
Connection: keep-alive
Content-Length: 32
sec-ch-ua: " Not;A Brand";v="99", "Google Chrome";v="91", "Chromium";v="91"
Accept: application/json, text/plain, */*
sec-ch-ua-mobile: ?0

Accept-Encoding: gzip, deflate, br

I get a 405 Not Allowed Response

But the request for /plugins succeeds with headers:

POST /api/scan/plugins HTTP/1.1
Host: 127.0.0.1:4399
Connection: keep-alive
Content-Length: 0
sec-ch-ua: " Not;A Brand";v="99", "Google Chrome";v="91", "Chromium";v="91"

I'm assuming it's something to do wth the Host and the nuxt.config.js proxy stuff but I'm not sure how it's supposed to be configured, given I'm using what's in the repo, I'd assume it is supposed to work?

I'm running using Docker if that impacts anything.
