Cause: The communication between the applet and the Forms Server process has experienced network problems, and communication has been broken.
Action: Add the parameter networkRetries to the forms configuration file. Set the value to a suitable number according to the network characteristics and needs. For example, networkRetries=30. This parameter specifies the number of times the Forms client should try reconnecting to the middle-tier before finally timing out.
Cause: If the error occurs even after setting up an appropriate value for networkRetries, it could be due to the ports on the web server restricted at TCP/IP level.
Action: A socket connection requires a port at each end. If the port is closed it causes the communication stoppage. Firewall and proxies are used to protect the ports. Unblock the ports on the Web server.
