rasdial changing username and password fails establishing network connection of vpn?

I was using this command to create a new vpn

Add-VpnConnection -Name "Connection_Name" -ServerAddress "Server_Address or IP" -TunnelType "Ikev2" -EncryptionLevel "Optional" -AuthenticationMethod Eap -SplitTunneling -RememberCredential -PassThru

--The connection created successfully.

Then to modify the vpn connection

Set-VpnConnection -Name "Connection_Name" -ServerAddress "Server_Address or IP"

--The server address changes successfully

Then for setting the username and password

Set-VpnConnectionUsernamePassword -connectionname "Connection_Name" -username "Your_Username" -password "Your_Password"

It changed if check it in the UI Interface of vpn connection in windows.

But when I try to connect with command--

rasdial "Connection_Name" "Username" "Password"

--It fails to connect the username and password doesn't changes. I find that out from the server. But if I try to connect from the UI interface. The username and password takes new ones and sets it. Then if we run the command to connect again it's successfully gets connected.

So, my question is does the username and password gets store into some sort of cache. If so how can I change it to new one? If there is other module which changes username and the password better?
