Nebula Site-to-Site SD-VPN between USG Flex and USG Flex H doesent work

KMZ

I have an issue with the Nebula VPN between a USG Flex H and a USG Flex.
No connection is being established via the Nebula SD-VPN. Connections using a Manual-link VPN are working.

These errors are in the Log.

All my USG Flex without H are Working with Nebula SD-VPN.

Can anyone help?

Hi @KMZ

Could you help to enable Zyxel support access and share your organization's name so we can access to check?

Thank you.

Hi @KMZ

This is because the H side VPN DDNS didn't update. This is a bug on firmware. I will provide you the fix via private message.
