Why does creating an instance of OkHttpClient take so long?

I've got this code on an Android 2.3 Gingerbread device which takes like 30 seconds.

I run it in async task away from UI thread (but it doesn't make a difference where I run it)

long startTime = System.nanoTime();
OkHttpClient client = new OkHttpClient.Builder()
        .followRedirects(false)
        .build();
long clientBuilt = System.nanoTime();
Log.d("API", String.format("Created OkHttpClient, it took %f milliseconds", (clientBuilt - startTime)/1000000d));

D/API: Created OkHttpClient, it took 30814.207720 milliseconds

I have up-to-date version of OkHttp for this Android version: 'com.squareup.okhttp3:okhttp:3.12.0'

Edit:

After applying Martin's suggested code: .connectionSpecs(Collections.singletonList(ConnectionSpec.CLEARTEXT))

and running a call to the server I get an exception:

java.io.IOException: unexpected end of stream on Connection{motoactv.com:443, proxy=DIRECT hostAddress=motoactv.com/69.10.180.44:443 cipherSuite=none protocol=http/1.1}

Such old API do not support SNI yet; enforcing plain-text HTTP might help:

OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Arrays.asList(ConnectionSpec.CLEARTEXT))
    .followRedirects(false)
    .build();

Stepping into the OkHttpClient.Builder should also tell, where exactly it gets stuck.
