Hi All, I am using HAProxy as a proxy server for my client towards the origin server via https. Everything work fine with TLSv1.2 however I need to use TLSv1.3 and in this case origin server send me back "403 Forbidden" because of :
SSL Library Error: error:14268117:SSL routines:SSL_verify_client_post_handshake:extension not received As I understand HAProxy do not send in Client Hello "verify_client_post_handshake" extension. Is it possible to configure somehow? Thanks Peter
