Cannot create a VPN connection

Hello,

I am trying to create a VPN site to site between my internal SonicWall device and Microsoft Azure.

I make a test with a new Azure Virtual network (classic) and it works.

But when i try to create a VPN with my Azure Production Virtual Network (classic) it don't works.

I check on the logs from my SonicWall and it says : No VPN policy for peer Gateway.

Did you already had this type of error ?

Thanks
