Description

Hello,

I have an problem, when running NiFi on Docker behind a reverse proxy (TinyProxy).

TinyProxy configuration adds three headers. NiFi is working on the same host on port 8080.

tinyproxy.conf
...
AddHeader "X-ProxyHost" "public.domain.com"
AddHeader "X-ProxyContextPath" "/path/to/nifi"
AddHeader "X-ProxyPort" "443"
ReversePath "/" "http://localhost:8080/"

I can access NiFi through https://public.domain.com/path/to/nifi/nifi/ and NiFi works fine, but I'm getting sometimes a popup, which states, that is cannot GET /nifi-api/flow/bulletin-board. For ex. I happens, when I try to view configuration of a Controller Service.

I recognized, that this request is made directly to NiFi and not through the reverse proxy. It looks, that it ignores the X-Proxy headers.
