azure site to site vpn setup connected but no traffic either way

hi team,

I have setup vpn connection between my azure portal and on-premises windows server 2019 machine (rras server), however i am not seeing any traffic. My setup is as follows:

my azure vm has private ip of 10.1.0.4 and public ip of 20.180.x.x.

my on-premises windows server

ethernet adaptor

ip add : 10.0.2.15

netmask 255.255.255.0

gateway 10.0.2.2

ppp adaptor

ip add 169.254.0.x

netmask 255.255.0.0

my azure vm network details

ip add v6 10.1.0.4

netmask 255.255.255.192

gateway 10.1.0.1

from windows server ,

ping 10.1.0.4 fails as request timed out

from azure vm 

ping 10.0.2.15 fails as request timed out

I can rdp and ping public ip address of azure vm from windows server
