HA cluster running 23.7.5 will not update to 23.7.6

[zz00mm]

All,
     I haven't looked into this much yet. I have a newly created HA cluster that was installed with 23.7 and upgraded to 23.7.5 before creating an HA cluster. The GUI shows pending update available, but when you click to proceed to upgrade it goes thru the process and says no updates available.
     I know updates are available as several standalone OPNsense 23.7.5 boxes showed the same pending update and they updated to 23.7.6.
     Any suggestions on what to troubleshoot? I've done the following so far.
     1) attempted to update from passive node, no success.
     2) attempted to update from active node, no success.
     3) put node1 (active) into maintenance mode and update, no success.
     4) change update server selection, no success.
     5) perform all update items via console, no success.
     6) attempted to update via pkg upgrade, no success.
     
     It's strange that standalone(s) will update, but the HA cluster will not.

It's all in the docs

Updating a CARP HA Cluster

Running a redundant Active/Passive cluster leads to the expectation to have zero downtime. To keep the downtime at a minimum when running updates just follow these steps:

    Update your secondary unit and wait until it is online again

    On your primary unit go to Interfaces ‣ Virtual IPs ‣ Status and click Enter Persistent CARP Maintenance Mode

    You secondary unit is now MASTER, check if all services like DHCP, VPN, NAT are working correctly

    If you ensured the update was fine, update your primary unit and hit Leave Persistent CARP Maintenance Mode

With these steps you will not lose too many packets and your existing connection will be transferred as well. Also note that entering persistent mode survives a reboot.

Thanks for the input, I forgot to mention in my initial post that I did try the passive node first.
Also on the primary node, I did put it into CARP maintenance mode and update found nothing to install.
Even rebooted the primary node while in CARP maintenance mode and update found nothing to install.

I'll look into this later. I did do some trickyness to these units. I moved /var & /tmp off the SSD onto second hard drive, this should not be the cause I hope.

Even turned IPv6 off to see if that helped with no luck. It's strange how the cron job runs everynight to check for updates and changes the status on the home page, then doesn't update anything.

Maybe I'll built up some VMs and see what happens.

I do have 1 strange item with this HA cluster.
Hulu & ParamountPlus will not stream thru this cluster.
They stream fine thru an old Atom CPU not in HA cluster and thru other standalone OPNsense FWs. And other streaming services work just fine. I'm going to packet capture it and see what it looks like.
