Hi all,
How to fix 500 Invalid Port Command error when you have a TV Tuner Card installed and a Virtual Private Networking enabled in Windows 98?
Receive Failed … 500 500 Invalid PORT Command result = 2
OK
Hope to hear from you.
Thanks.
Hello Jedei,
To resolve the error that you are getting you can try using the following workarounds:
Solution 1:
Try upgrading the router, the nat device firmware and any other firmware that might be the possible causes to that error and see if that will resolve the issue.
Solution 2:
In case the Firewall Network Address Translation (NAT) is not able to correctly change the IP addresses mentioned here: https://support.microsoft.com/en-us/help/281193/ftp-error-500-invalid-port-command, then the server will come up with the error message on the command. The issue is most likely to occur when the FTP server changes from listening on port 21 to another port that is a bit higher.
Regards,
Carl
