Solucionado
Buscando no stackoverflow tentei adicionar o seguinte codigo no onCreate
SSLContext sslContext;
try {
sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
sslContext.createSSLEngine();
} catch (NoSuchAlgorithmException | KeyManagementException e) {
e.printStackTrace();
}Mas sigo com o mesmo erro de conexão. Alguma ideia do que pode ser?
Reiniciei o servidor e a conexão foi feita, mas agora aparece uma mensagem de erro no terminal do servidor.

O que pode ser?
Encontrei a solução!
Adicionei o seguinte código no manifest
<manifest ...>
<uses-permission android:name="android.permission.INTERNET" />
<application
...
android:usesCleartextTraffic="true"
...>
...
</application>
</manifest>
