retrofit: Crash with UnknownHostException

Hi there, I have a crash report from Fabric. Here is the stack info:

Fatal Exception: java.net.UnknownHostException: Unable to resolve host "www.telecineplay.com.br": No address associated with hostname

But in the source code of CallExecuteOnSubscribe, all exception should be cached, I’m really confused why the crash happened instead of calling onError().

Here is my dependencies:

RETROFIT_VERSION = "2.2.0"
implementation"io.reactivex:rxandroid:1.2.1",
implementation "io.reactivex:rxjava:1.3.0",
implementation "com.squareup.retrofit2:adapter-rxjava:$RETROFIT_VERSION"
implementation "com.squareup.retrofit2:retrofit:$RETROFIT_VERSION"

Can you help pls? Thanks in advance.
