Resolution

• It may be due to connectivity issues, such as firewall or network-related problems. Please check for any internal firewall or network issues in the environment
• Configure session timeout settings. 

In order to implement session timeout, you must update the following 3 files:

Apache Tomcat location\config\web.xml
Here you need to set the session timeout value: (example 5 minutes)

<session-config>
        <session-timeout>5</session-timeout>
    </session-config>

Apache Tomcat location\webapps\awi\config\uc4config.xml
Here you will turn off tcp keepalives

<tcpip_keepalive>0</tcpip_keepalive>

Apache Tomcat location\webapps\awi\config\configuration.properties
Here you will set:

closeIdleSessions=true

Restart Tomcat for changes to take effect.
