kubo behind haproxy unable to return deserialized responses about kubo

[lidel]

@chrisschaub I was not able to reproduce.

You did not share your HAProxy configuration, but based on informaiton shared, this is likely a misconfiguration on your end (haproxy config and/or kubo config lacking explicit Gateway.PublicGateways defined).

Some things you may want to try:

• use Gateway.PublicGateways configuration in Kubo to safelist domain(s) that you use with haproxy
  • see Gateway recipes for common examples
• inspect your HAproxy configuration and make sure it correctly forwards the Host header
  • You can also hardcode Host by passing explicit X-Forwarded-Host and X-Forwarded-Proto – see the first example in recipes

Lmk if any of this helped, or provide full configuration that reproduces the bug your experience (we can't help without reproduction steps). Thanks!

Assuming I don't need public gateways if I'm only trying to retrieve a local pinned ipfs file. I"ll check my haproxy config, but it's really simple:

global
  stats socket /var/run/api.sock user haproxy group haproxy mode 660 level admin expose-fd listeners
  log stdout format raw local0 info
  maxconn 50000

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

frontend ipfsgwhttp
  # listen for HTTP traffic
  bind :80
  # listen for HTTPS traffic, load certificates from an EFS directory
  bind :443 ssl crt /mnt/efs/haproxy/certs/
  # redirect HTTP to HTTPS
  http-request redirect scheme https unless { ssl_fc }
  # the pool of backend servers
  default_backend ipfsgw

backend ipfsgw
  server s1 gw-kubo:8080 check

Ok, the fix was to add

  option forwardfor
  http-send-name-header Host

to haproxy. Thank you for your patience.
