Traefik v1 on EKS v1.18 - Bad request when enabling ProxyProtocol


Was wondering if the latest Traefik v1 release (v1.7.26) supports ProxyProtocol V2?
I'm trying to enable it with an NLB on AWS and it returns 400 constantly.

Everything is set up on Traefik side and ProxyProtocol works well if I use Classic Load Balancer instead.
