Troubleshooting

My issue:
Whenever I turn ON proxy protocol version 2 on cloud load balancer, I encountered an issues in nginx-controller pod logs

2025/04/17 19:33:02 [error] 36#36: *6466 header is too large while reading PROXY protocol, client: 10.244.72.64, server: 0.0.0.0:443

2025/04/17 19:33:03 [error] 36#36: *6507 header is too large while reading PROXY protocol, client: 10.244.250.0, server: 0.0.0.0:443

2025/04/17 19:33:03 [error] 39#39: *6508 header is too large while reading PROXY protocol, client: 10.244.47.192, server: 0.0.0.0:443

How I encountered the problem:
With version 1 is working fine.

Solutions I’ve tried:
I tried increasing the client-header-buffer-size: 128k, still did not work.
My config:
server {
server_name myserver.example.com ;

	listen 80 proxy_protocol ;
	listen [::]:80 proxy_protocol ;
	listen 443 proxy_protocol ssl http2 ;
	listen [::]:443 proxy_protocol ssl http2 ;

Hi, can you confirm that you are using the NGINX Ingress Controller, as you mentioned this in the title? If so, can you let us know the version you’re using, and can you share with us your deployment yaml?
