CertPathValidatorException：未找到证书路径的信任锚。 在 android 中更新 gradle 和 gradle 插件后

Question

I try to check SSL, by this code (and work successfully):

OkHttpClient.Builder httpBuilder = new OkHttpClient.Builder();
CertificatePinner certificatePinner = new CertificatePinner.Builder()
        .add("example.com", "sha256/S4AbJNGvyS57nzJwv8sPMUML8VHSqH1vbiBftdPcErI=")
        .build();
OkHttpClient client1 = httpBuilder
        .certificatePinner(certificatePinner)
        .build();
Retrofit retrofit1 = new Retrofit.Builder()
        .client(client1)
        .baseUrl("https://example.com/").addConverterFactory(GsonConverterFactory.create()).build();
samaniumRestApi2 userClient = retrofit1.create(samaniumRestApi2.class);
Call<Object> call = userClient.maintenanceMode(requestmaintenanceModeCheck);
call.enqueue(xxxxxxxxxxxxx);

and I get error by change base url to:

https://example.com:448/

or

https://subdomain.example.com/

and error is :

CertPathValidatorException: Trust anchor for certification path not found.

please save me

这意味着证书是为www.example.com颁发的，因此对于whatever.example.com 来说是不可信的——这个服务器需要正确的签名证书
