Histórico de mensagens sobre ssl em pix

O exemplo da GN para Nginx separa o mTLS só em um path:
server {
#
# ...
#
listen [::]:443 ssl ipv6only=on;
listen 443 ssl;
ssl_certificate server_ssl.crt.pem;
ssl_certificate_key server_ssl.key.pem;
ssl_client_certificate /root/chain-pix-webhooks-prod.crt;
ssl_verify_client optional;
ssl_verify_depth 3;
#
# ...
#
location /webhook {
if ($ssl_client_verify != SUCCESS) {
return 403;
}
rewrite ^(.)$ /webhook;
}
}

Obrigado pelo retorno Rubens, reparamos isso na documentação mas nosso ambiente compartilha de um outro certificado SSL

Tente colocar o trecho SSLCACertificateFile /etc/ssl/certs/chain-pix-prod.crt fora do

Your SSL library does not have support for per-directory CA

Não consigo dar restart no apache com a configuração

No Apache eu achava que era Directory, mas é Location mesmo:

## Se preferir deixar apenas uma rota de sua url para notificações você pode adicionar:

SSLVerifyClient none

SSLVerifyClient require
SSLVerifyDepth 3

adicionei e agora a página da o erro ERR_BAD_SSL_CLIENT_AUTH_CERT

Tens que adicionar no arquivo de conf meudominio-le-ssl.conf

SSLVerifyClient require
SSLCACertificateFile "/etc/ssl/certs/chain-pix-prod.crt"
SSLVerifyDepth 3

erro do apache "SSL routines:SSL_verify_client_post_handshake:extension not received"

https://www.php.net/openssl_pkcs12_read

No PHP use o openssl_pkcs12_read

fui converter o certificado usando o openssl.exe e me pediu uma senha do certificado

openssl.exe

O SSL Test parece correto:
