Comienza con pom.xml y la ruta del error a través de InfluxUtils.connect y SinkToInflux.open. Compara las exclusiones de dependencias indicadas y la configuración classloader.resolve-order con los entornos local y de clúster; después, sigue la causa completa de inicialización de okhttp3.OkHttpClient. Se considera terminado cuando se haya identificado una causa reproducible y se haya documentado o implementado una solución para el fallo del clúster.
