This error message indicates that a Java program was unable to establish a connection to a remote server or service. The most common causes of this error are:
1. The remote server or service is not running or is not accessible from the network.
2. The firewall or network settings are blocking the connection.
3. The port number or IP address is incorrect.
To resolve this issue, you can try the following steps:
1. Check that the remote server or service is running and accessible from the network.
2. Check the firewall and network settings to ensure that the connection is not being blocked.
3. Double-check the port number and IP address to ensure that they are correct.
4. If none of the above steps work, try restarting both the Java program and the remote server or service.
