Troubleshooting: Browser Loading Issues (Error 404, Port Conflicts)
Observed behavior:
WDServer reports a 404 error in your browser or does not load in the browser, and there are no errors in the running WDServer application terminal.
Cause:
Another application or process on the PC tries to use the same port as WDServer for the browser interface (TCP port 5000). A common conflict is Vector tools (CANalyzer, etc.)
Solution:
Find the the application or service which is also trying to use the same port, and close it.
Open Windows Command Prompt and run the command:
netstat -noa | find "5000"
Look for multiple entries in the list marked as "LISTENING". This indicates a conflicting application.
Use the rightmost column, the PID, and then open Task Manager (Ctrl-Alt-Delete).
The PID of the offending process or application will be shown in the Details column in Task Manager.
