為什麼 Chrome 會忽略我證書中的 X509v3 主題備用名稱？

我有一個包含 X509v3 主題替代設置的證書，但 Chrome 67.0.3396.99 說缺少主題替代名稱，即使它看起來包含在證書中。

這是證書的 X509v3 部分openssl s_client -showcerts -connect www.mysite.org:443 </dev/null 2> /dev/null | openssl x509 -noout -text

   X509v3 extensions:
           X509v3 Basic Constraints: 
               CA:FALSE
           X509v3 Key Usage: 
               Digital Signature, Non Repudiation, Key Encipherment, Data Encipherment
           X509v3 Subject Alternative Name: 
               DNS:www.mysite.org
           X509v3 Extended Key Usage: 
               TLS Web Server Authentication
           X509v3 Basic Constraints: critical
               CA:FALSE
           X509v3 Subject Key Identifier: 
              <redacted>

證書的主題是Subject: CN = www.mysite.org.

我是否錯過了 Chrome 期望的一些額外的 X509v3 設置，因此它會接受 SAN？

Chrome 67 已經很老了，但是您的證書有兩個違反 RFC5280 4.2 的 BasicConstraint 擴展，如果我複制該錯誤（手動！）我最新的 71.0.3578.98 表現出相同的症狀：NET::ERR_CERT_COMMON_NAME_INVALID 和 ‘advanced ’ 聲稱 ‘證書沒有指定主題備用名稱’ - 即使我’繼續 $site (unsafe)’ 然後點擊掛鎖並查看證書，它被確認存在 SAN 並且正確。

因此，用於創建此證書的任何方法都以某種方式被破壞，但 Chrome 的處理方式並不理想。

補充：根據評論，這是我最新的測試數據，其中一個 BC 有效，而兩個 BC（兩種形式：關鍵和非）失敗，Chrome 和 Firefox esr：
