我们在Google Cloud上提供了IBM MFP 8.0.0.00-20171220-1341版本。 我们正在使用身份验证适配器进行登录。
在进行登录时，我们收到java.net.SocketTimeoutException：超时异常。 请检查以下日志。

什么是阻塞，因为我们遇到了间歇性问题。是由于Google Cloud发生此问题吗？
答案 0 :(得分：0)
这可能与Google Cloud无关。在安全检查中，您似乎正在以下位置调用后端：
at com.mfpauth.impl.Authentication.callAdapterWebService(Authentication.java:118)
为此，您正在使用okhttp库。
okhttp3库的默认超时为10秒。您可能需要增加超时值，并检查是否可以解决问题。
