Hello, i tested the VPN headend and user/pass you provided and this connected with no problems. Check the port is not being blocked by your firewall or ISP. The port range will be anywhere from TCP 20100 through TCP 20354. Give that a try and you should be good to go. If that's not working, keep in mind VPNs also use TLS (TCP 443) and DTLS (UDP 443). Though typically these are open in most organizations.

it connects when i connect through mobile app on my android but not on windows machine.

i have added firewall rules to allow ports as suggested.

can you tell me some other way to allow those ports.

It is either one of two things.

Turn of IPV6 on your WIFI and LAN adaptors on your Windows machine and test again
I am going to guess that your cell phone is using another provider, hence this is why this works and your ISP does not and appears to block the destination, this I have seen in a few comment here before

Hope this helps.
