ReadyNAS Ultra 2 - can't access because it uses an unsupported protocol

Question

I have a ReadyNAS Ultra 2 (RNDU2000) running Firmware 4.2.19. I haven't really used the NAS in the last couple of years, however it has been plugged into and running on my home network since being installed.

I'm running a desktop running Win 11.

Now trying to access the NAS, I'm getting unsupported protocol errors using Edge, Chrome & Firefox.

RAIDar can see the NAS, but won't allow me to update - see attached picture.

I'm guessing I have to up the firmware in the NAS, but unable to access the NAS via the desktop.

Any clues / ideas on how to either get a data connection with the NAS and /or update the firmware ?

The current version of FireFox will work if you set&nbsp;security.tls.version.min&nbsp;to 1 (browse to about:config and search for the setting).

As you own an Ultra 2, I think it's possible to convert to an ReadyNAS OS 6 - it won't make a brand new and modern NAS, but still much better than the legacy OS 4.
