Hey Anthony

Can you perform a configuration sync?

Have you checked so that the BIG-IP devices are listening over the correct failover unicast address/port? Run the following command on both devices:

netstat -na | grep 1026

The output should look like this:

[root@bigip02:Active:Changes Pending] log  netstat -na | grep 1026

udp        0      0 192.168.1.32:1026           0.0.0.0:*
udp        0      0 10.10.10.32:1026            0.0.0.0:*

This setting is configured per device under: Device Management ›› Devices ›› [BIG-IP Hostname] ›› Failover Network.

I think that if it's missing it could present the scenario you have.

I hope this helps! 🙂
