Welcome to our community! :smiley:

You will need to check your full Elasticsearch log to see what is happening there.
Please also format your code/logs/config using the </> button, or markdown style back ticks. It helps to make things easy to read which helps us help you :slight_smile:

Hello there!
In your log we can see:

My question is:
how did you set up heap memory size?
You can check it in file:

/etc/elasticsearch/jvm.options

Lines:

## -Xms4g
## -Xmx4g

should be uncommented and values should be set for your needs.
