ProtocolException: Too many follow-up requests: 21 with Proguard and OkHttp 3.0 in Android
<p>I am creating an app using Retrofit 2.1.0 and OkHttp 3.4.2.</p>

<p>In debug mode with minifyEnabled set to false everything works perfectly but as soon as i change minifyEnabled to true i get the following exception:</p>

<pre><code>HTTP FAILED: java.net.ProtocolException: Too many follow-up requests: 21
</code></pre>

<p>My Proguard rules for OkHttp are as follows:</p>

<pre><code>-keep class com.squareup.okhttp3.** {
    *;
}
-dontwarn okhttp3.**
-dontwarn okio.**
</code></pre>

<p>I can't understand why this exception is thrown and i do not understand why the app is seems to be making 21 follow up requests. Can anyone help me?</p>
