Briefly, this error occurs when Elasticsearch fails to bind to the specified port range during startup. This could be due to the port being already in use, insufficient permissions, or network restrictions. To resolve this issue, you can try the following: 1) Check if the port is already in use by another service and if so, change the port. 2) Run Elasticsearch with a user that has sufficient permissions. 3) Check your network settings and firewall rules to ensure they are not blocking the port.
