cant start SSLVPN because port 4430 in use

favianbayu Lv1Posted 2024-Jun-25 12:56

Dear All

I found an issue when I wanted to start the SSL VPN service on NGAF
there's a notice that port 4430 is in use shown in the screenshot below


Another port setting is still the default.
We tried to change the SSL VPN port to 4431 but the notice of '4430 port in use' is still shown
when we try to change back to 4430, we can't (because it is in use)

I don't know what the ports are used for, is there anyone happen to have the same issue?
Or can we change to another port? And what port do you guys suggest using for SSL VPN?

Thankyou

HiHi,

Please use the Resource Monitor (GUI) in the Windows OS to check the listening port by following these steps:

1. Press Win + R to open the Run dialog box, then type 'cmd' and press Enter.
2. In the command prompt, enter 'Perfmon /Res' and press Enter.

Once the Resource Monitor is open, navigate to the Network tab to view all network connections, listening ports, and associated applications.
Please try changing to a different port for testing once again. Additionally, I have attached the Sangfor NSF SSL VPN configuration guide for your reference.

Hi,

Terminate the Conflicting Process:
On Windows, open Task Manager, go to the "Details" tab, find the PID from the previous step, right-click on it, and select "End Process" or "End Task".
On Linux or macOS, use kill PID where PID is the Process ID obtained earlier.
