Hi

 

A few thoughts

 

Are you using a dedicated HA VLAN. Do you have connectivity on this VLAN, can you ping?

 

Does the Self IP that you are using for HA have the correct port lockdown setting? Set to Allow Default to be sure, you can harden this later if required

 

Under Devices, has the Configsync and Device Connectivity been configured correctly on both devices? Using IPs from the correct VLAN

 

Does the device cert on each box look OK - is it in date etc

 

If any of these need changing then do so and then re-establish the trust between the devices and redo the device group
