Certificate/SSL termination problem

@ondoroshenko wrote:

Hello, experts.
I am configuring haproxy for load balancing between 2 websites. Websites are secured with https self-signed certs only.
I believe I configured haproxy in pass-through mode. For frontend I am using http with redirect, but it is not a requirement.

With my current setup I have to accept certificates with every new session.
It is very annoying. I want to accept certificates only 1 time. Please have a look at my config and suggest what I am doing wrong.
Thank you
