FAIL sni_server [/work/php-src/ext/openssl/tests/sni_server.phpt] 

PHP Version

master

Operating System

Ubuntu 24.04

ext/openssl/tests/sni_server.phpt と、191 行目付近にある ext/openssl/tests/ServerClientTestCase.inc の周辺ロジックから始めてください。PHP master で断続的な失敗を再現し、peer certificate が利用できない理由を調査してください。報告された warnings や予期しない NULL 出力なしでテストが安定して実行されれば完了です。
