Scenarion:
I was trying to configure non-Nebula VPN between two different Nebula orgs. The configuration was configured correctly, but the event logs show "Phase 2 policy mismatch".
What happen?
Answer:
It could be remote subnet is mismatched.
For Site_A, there are 3 local interfaces enabled for Site-to-Site VPN, and the firewall will take the first interface as the local subnet which is not matched to the remote subnet for Site_B.
How to fix: Edit IPSec Policy, and input the correct subnet to VPN tunnel interface
