Caused by: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
... 32 more报错原因：证书链验证失败，细节如下：
Let's Encrypt 的根证书 ISRG Root X1 发布于 2015 年，而 Android 5.x 发布于 2014 年，其内置的信任证书库（CA store）未包含该证书。Android 7.0+ 才默认信任 ISRG Root X1。 所以5-7的系统无法在本地信任库中找到根证书，导致 Trust anchor not found 错误。
