Answer 1

try this command in your project root directory.

sudo systemctl daemon-reload
sudo systemctl restart elasticsearch

and if this doesn't work, try restarting your system and if that doesn't work, try

run this command in terminal

sudo nano /etc/elasticsearch/jvm.options

-Xms4g
-Xmx4g

and change this value according to your RAM, if 16 GB ram then set value half of your ram number

-Xms8g
-Xmx8g
