Android System.err:javax.net.ssl.SSLPeerUnverifiedException:Hostname XXX即使在添加网络安全配置后也未验证

我已经在清单中添加了网络安全配置，但仍然收到主机名未验证错误

<manifest ...>
   android:networkSecurityConfig="@xml/network_security_config"

    <domain includeSubdomains="true">XXX</domain>
    <trust-anchors>
        <certificates src="system" />
        <certificates src="user" />
        <certificates src="@raw/xxx"/> This is a .cer file
    </trust-anchors>
