If you have two Nebula VPN subnets but the tunnel connection is failing, there are several potential causes to investigate. Follow these steps to diagnose and resolve the issue:

Please be aware that Nebula will take the first subnet as the primary rule in the VPN policy, and the second one will be added to the policy route in the background automatically.

If your peer site subnet, for instance, is 192.168.217.0/24, please disable the first rule and then enable it again. This should resolve the issue.
