HTTP mode with SSL for Geth RPC

Help!
1

I am trying to configure HA Proxy for Geth Ethereum RPC nodes with SSL enabled to test.example.com

I am running HA Proxy via docker image: haproxytech/haproxy-ubuntu:3.0

I have confirmed the backends work, and I have additionally confirmed a similar HA Proxy configuration without SSL (http). I believe there is something happening with how the requests are being forwarded via POST which is causing issues that I am not aware of.

There is no firewall issues either I believe.

Additionally I have confirmed that the SSL cert works in another HA Proxy config on the same server which accesses Prysm nodes (Ethereum consensus layer).

I test the HA Proxy via

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' https://test.example.com:8545

Invalid Host

Here is my .cfg file

global
  stats socket /var/run/api.sock user haproxy group haproxy mode 660 level admin expose-fd listeners
  log stdout format raw local0 info
  insecure-fork-wanted
  external-check

defaults
  mode http
  timeout client 10s
  timeout connect 5s
  timeout server 10s
  timeout http-request 10s
  log global

frontend stats
  bind *:8404
  option httpclose
  http-request use-service prometheus-exporter if { path /metrics }
  stats enable
  stats uri /stats
  stats refresh 10s

frontend frontend
  bind :80
  bind :443 ssl crt /bin/cert_and_key.pem
  http-request redirect scheme https unless { ssl_fc }
  mode http
  default_backend backend

backend backend
  server node-1 1.1.1.1:8545

And my docker command is

docker run -d \
  --name ethlb \
  -v geth-https.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro \
  -v /etc/letsencrypt/live/test.example.com/cert_and_key.pem:/bin/cert_and_key.pem \
  -p 8545:443 \
  -p 8404:8404 \
  haproxytech/haproxy-ubuntu:3.0

I know there must be some specific frontend options I am missing. Can someone please assist me to get this working? Thanks!
