Problem with elasticsearch when deploying liferay ce 7.4 in kubernetes - elasticsearch

Question

I'm trying to deploy liferay ce 7.4 in kubernetes and I can't connect elasticsearch 7.14.0. I get the following error:
2022-03-19 20:06:29.375 ERROR [main][ElasticsearchEngineConfigurator:93] bundle com.liferay.portal.search.elasticsearch7.impl:6.0.30 (1134)[com.liferay.portal.search.elasticsearch7.internal.ElasticsearchEngineConfigurator(3789)] : The activate method has thrown an exception

I have verified that the elasticsearch is correctly deployed by running: kubectl port-forward search-59fcc9c4f6-brhcv 9200

To configure the elasticsearch connector I followed the page: http://www.liferaysavvy.com/2021/07/configure-remote-elasticsearch-cluster.html and https://liferay.dev/blogs/-/blogs/deploying-liferay-7-3-in-kubernetes
Someone could help me?
Thanks in advance.
