AP121's stuck at HiveOS 6.4r1d

[netadmin21]

I have a HiveManager Connect account and have twelve AP121s. Five of them are stuck on HiveOS 6.4r1d. When I upgrade HiveOS it displays a "Device Update Failed" regardless of HiveOS version I choose.

Can someone please point me to the right direction please? Is there a way to get the appropriate .img file so I can do a manual update of the firmware?

Any help greatly appreciated.

Make sure that when you try and connect you use http://[ip] rather than just going direct on the IP address.

You will get a message about NET::ERR_CERT_AUTHORITY_INVALID but you can just go advanced and then proceed (chrome)

Thanks for sending the links and making the necessary files available. I've downloaded the files, but unfortunately I can not connect to the Web UI of these devices. When I try, I get an error message stating:
10.0.0.27 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Unsupported protocol
The client and server don't support a common SSL protocol version or cipher suite.
I've tried to connect in Chrome, EDGE, and IE11, all with a similar result.
These devices all have red circles with an X in it and the notation "Device Update Failed".
I'm wondering if there is a set of CLI commands that would work thru a serial connection in PuTTY by which I could accomplish the updates.
I will be on vacation and unable to further respond for a couple of weeks, but would appreciate any further help you can give.
Thanks in advance.

Thank you for reaching out, I've emailed you directly with the files you'll need and a guide that reviews how to update device firmware via the Web UI instead of the HiveManager GUI. You'll need to update the devices to 6.5r3 minimum to manage them in HiveManager.
