VPN disconnect continuously - How to resolve?

@Jey Does an error message appear?

What kind of internet connection did you get? Mobile?
Have you tried temporarily disable your firewalls (laptop/router)?
Do you have a VPN server installed or just trying to connect through a VPN client?

Thanks for your reply

Im using NOS Wifi internet connection from the NOS Router.
I disabled Firewalls in my laptop
VPN server is already installed, previosuly i use Vodafone HotSpot, that time VPN works perfectly but, after taken NOS internet connection its not working.

To get the VPN Server to work you gonna need to have Port Forwarding configured in the NOS Router. Did you accomplished that? Did you assign a fixed IP to the device where you are running the server?
What about the Router Firewall?

Just now i entetered my router control panel there it was selected as "Typical Security
Inbound Policy: Reject.
Remote Administration settings will override the security inbound policy.
Outbound Policy: Accept."
then now i choose
Minimum Security
Inbound Policy: Accept.
Outbound Policy: Accept.
but, no improvement

Enter your router and go to >serviços > firewall > encaminhamento de portas (in the right side of the panel) (Services > Firewall > Port Forwarding)
Then chose new entry > device to forward to > chose the aplication (any or user defined if not listed) > port to forward to
Press OK. Some seconds later the port will be open.

Maybe this article will help you, but it seems to me that this problem is due to the unstable network.
