Hi,

I am struggling to get things working on my Plesk server. I have succesfully installed Elasticsearch and see this error in te log:

How did you install Elasticsearch? Did you follow the instructions [available here](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/install-elasticsearch.html)? What is the specification of the host?

Hi, I just 5 minutes ago fixed things. I followed this [Elasticsearch could not find Java and now won't start](https://discuss.elastic.co/t/elasticsearch-could-not-find-java-and-now-wont-start/173973/16)

But thanks for the answer.
