java.net.SocketTimeoutException: Read timed out under Tomcat

A java.net.SocketTimeoutException: Read timed out error can occur when a connection to a server is blocked by a firewall or if the server is experiencing high load and is unable to process requests in a timely manner.

To troubleshoot this error when running under Tomcat, you can try the following steps:

  1. Check the Tomcat logs for any errors or warnings that may indicate the cause of the timeout.

  2. Check the network configuration of your Tomcat server to ensure that it is not being blocked by a firewall or network security device.

  3. Check the server load and resource utilization to ensure that the server has sufficient resources to handle incoming requests.

  4. If the problem persists, you may need to increase the socket timeout setting in your Tomcat configuration. To do this, you can edit the connectionTimeout attribute in the Connector element of the server.xml configuration file. For example:

<Connector connectionTimeout="60000" ... />

This sets the connection timeout to 60 seconds. You can adjust this value as needed to allow more time for the server to respond to requests.

I hope this helps! Let me know if you have any questions.
