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?
Thanks for your reply.
I dont know how to do Port Forwarding?
Yes assigned fixed ip to my vpn server

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.

Hi @Jey,

I’ve noticed that you’ve chosen one of the predefined options on the router, but I have it for me that it would be better to use a user-defined root instead, you know?
However, what I see as a possible problem is the fact that you have not defined the same port, ie you defined the following routing:
TCP Any> 3389
TCP Any> 259
TCP Any> 7020

1 °) I advise you to define all the routes from and to the same port, like this:
TCP 3389> 3389
TCP 259> 259
TCP 7020> 7020

2) Is it sufficient to forward only the TCP protocol? I advise you to also forward the UDP protocol:
TCP 3389> 3389
UDP 3389> 3389
TCP 259> 259
UDP 259> 259
TCP 7020> 7020
UPP 7020> 7020

And remember, this is just an example based on the ports indicated in your previous comment. Are you sure these are the ports and protocols that your VPN server uses?

Hello. I have connected in a new location in Braga (wi-fi router 5.0 ) to NOS. The previous flat had MEO and the my VPN connection worked fine, but now it's always "frozen" after some time and I need to restart it (on my devices) many times. It makes my work almost impossible. 

router v5 v1 or v2?

My husband tried to talk to 16990 support today. Their answer is - we don't see a problem, so there isn't one. They can't replace the router either. They offered to terminate the contract for penalty, although less than 14 days had passed. Awfully 

Hello Anna, Have you tried sending messages to moderators?

I’ve send message to @Fórum 2 days ago

And NO it is not a some kind of WiFi/Lan-level problem. This picture from PC connected directly to Gigarouter bridge-mode (4-port).
