There are several ways to view connection error messages:
Connection failure indicator in Systems Information view |
---|
![]() |
Error: | ConnectException: Connection timed out: connect or UnknownHostException: <IP address or host name> |
---|---|
Explanation: | Incorrect IP or host name |
Actions: |
Verify entered IP address or host name is reachable from your machine: You can use the ping tool to check whether the IP address is reachable.
Look for messages appearing which start with Reply from <IP address or host name> such messages indicate that the address or host name is reachable from your machine. If you do not see such messages, or if you see Request time out. messages, then you need to speak with your network administrator. Note that in some cases, IP addresses which are accessible from your machine may not respond to ping if the administrator of the system has disabled this functionality (or network administrator has blocked this, for example using a firewall) - speak with your system administrators and/or network administrators to determine whether this is the case; if it is, using the ping tool will not provide any useful diagnostic information. |
Error: | ConnectException: Connection refused: connect |
Explanation: | File Manager® server not installed, incorrectly configured, or not running |
Actions: |
Verify File Manager® is running on chosen port: If you have the Telnet tool installed, you can use the Telnet tool to attempt to connect to the File Manager® server. To do this on a Windows XP machine, click the Start button, click on Run, type telnet <IP address or host name> <port> into the field of the run box, then click OK. To do this on a Windows Vista or Windows 7 machine, type the same directly into the quick search field at the bottom of the Start menu. If a black window opens and says it is Connecting and then goes blank, the File Manager® server is running on the entered IP address and port. If a black window opens and says it is Connecting and then disappears shortly after, or if you get an error message complaining that Telnet is unknown, cannot be found, or is an invalid command, then the File Manager® server is not running on the entered IP address and port. Verify File Manager® Configuration is correct: Speak to your mainframe system administrator to verify that the File Manager® server is installed and running correctly on the specified IP address or host name and port number. |
Error: | CommunicationSecurityException: Invalid authentication credentials |
Explanation: | Incorrect username and/or password |
Actions: |
Verify your username and password are correct: Try connecting with another tool or speak to your mainframe system administrator. |
Error: | NetworkException: Failed to communicate with the server because the server was unable to start your session under your user ID. You may not have the privilege to access the File Manager® server. Please consult your systems administrator. |
Explanation: | Entered user may not have the privilege to access the File Manager® server |
Actions: |
Attain the privileges required to access the File Manager® server: Contact your mainframe system administrator to make sure you are authorized to use the File Manager® server, and have your system administrator grant you the privileges required to access the File Manager® server if you are not currently authorized. |
