Message retry timeout. Check the connection between local and remote gateway endpoints.
We have a main office and 4 branch offices. The main office (M200) has BOVPNs to all four branch offices. Two of the branch offices (Site 2 and Site 3) have a BOVPN between each other as well. Last night the tunnel between Site 2 and Site 3 went down and I'm getting the error on both sides: Message retry timeout. Check the connection between local and remote gateway endpoints.
The tunnels from the Main office to Site 2 and Site 3 never went down and remain up. Can't figure out why I can't get the BOVPN between S2 and S3. No changes were made to any configurations. I attempted deleting the BOVPN between S2 and S3 and re-creating, but I still get the same error.
I can post the diagnostics in a reply as they are too long to post in here.
Any help on this would be greatly appreciated!
