Azure VPN connection fails with Failure error code:0x000035ed

-1

I have created an VPN connection from my Azure VNET to a third party on site VPN device. The connection unfortunately fails. I have configured logging in the VNET and get the following error:

Can anyone tell me what is wrong? I don't have any control over the VPN device, but make any Azure changes required.

This turned out to be to the Azure gateway using IKEv2 and the on-premises gateway using IKEv1. Updating the on-premises gateway fixed the issue.
