android - 如何解决崩溃 : Dns. java okhttp3.Dns$1.lookup？

Question

最近我开始收到这样的崩溃。没有更新有吊带。有谁知道什么会导致这个问题？谢谢。

com.squareup.retrofit2:改造:

改造版本=“2.6.1”；
retrofitConverterGsonVersion = "2.6.1";
retrofitAdapterRxJava2Version = "2.6.1"

    Dns.java line 39
okhttp3.Dns$1.lookup

如果服务器正常(很可能是)
所以这是一个在移动连接出现问题时抛出的正常异常。我认为您应该捕获异常并提醒用户检查他的连接。
请检查 okhttp repo 中报告的此问题
