cpanelSSL validation failure during ghost setup ssl
ACME Challenge Failures in Ghost CLI The ghost setup ssl command automates the acquisition of Let's Encrypt certificates and the corresponding Nginx configuration. This process relies on the ACME protocol, which requires the server to be publicly reachable via port 80 and 443 to validate domain ownership through DNS A-records. When the validation process fai
ghostHostname verification transition in OpenSSL 1.1.0
OpenSSL 1.1.0 introduced the X509_VERIFY_PARAM_set1_host and SSL_set1_host APIs to implement RFC 2818 hostname verification. Unlike previous versions where some tools performed implicit checks, this verification is not enabled by default in the library; applications must explicitly set the target host name to activate the check. This change affects how the s
opensslDBeaver Connection UI and PostgreSQL JDBC Driver: Which SSL/TLS and Authentication Settings Are Authoritative?
A DBeaver connection to PostgreSQL that succeeds locally but fails in production exposes an unresolved integration boundary between DBeaver's connection UI and the underlying PostgreSQL JDBC driver. The goal is to determine whether DBeaver's SSL/TLS and authentication selections are meant to generate a complete, authoritative JDBC property set matching the s

postgresqlOpenSSL CSR configuration for Subject Alternative Names (SAN)
When generating a Certificate Signing Request (CSR) using the openssl req command, standard subject fields are handled via interactive prompts or a basic configuration file. However, modern browser requirements necessitate the inclusion of Subject Alternative Names (SANs) to ensure certificate validity across multiple DNS entries or IP addresses. The goal is
Erlang inet DNS resolution and ssl certificate validation error separation
Goal: Determine whether an Erlang/OTP application can distinguish a DNS resolution outcome from a TLS certificate validation failure when connecting to a hostname that resolves to multiple addresses. The inet application may return several IPv4 and IPv6 records for one name, while the ssl application performs certificate verification only after a TCP/TLS han
SSL Handshake Failure during Client Certificate Verification in Dovecot
A Dovecot configuration requires mutual TLS (mTLS) to authenticate clients via certificates. While the ssl = yes and ssl_cert directives are configured for the server identity, the system must also validate the incoming client certificates against a trusted root. The current uncertainty involves the behavior of the ssl_ca directive when managing a complex tr
dovecotZend Http Client SSL certificate validation failure with custom CA bundles
The Zend\Http\Client (Laminas) relies on PHP stream wrappers to handle SSL/TLS handshakes. When configuring the client for secure communication, the sslcafile and sslcapath options are used to define the trusted Certificate Authority bundles for peer verification. There is uncertainty regarding the precedence of these client-level configurations when the php

zendSSL certificate validation failure during systemd-resolved DNS stub integration
On Arch Linux, integrating systemd-resolved typically involves linking /etc/resolv.conf to /run/systemd/resolve/stub-resolv.conf to utilize the local DNS stub listener at 127.0.0.53. When this configuration is active, certain applications may encounter SSL/TLS handshake failures if the DNS resolution process introduces latency or returns unexpected records t
