I see, I figured out the link issue: it should be https://raysfiles.com/.. NOT http (i.e. secure vs. non-secure). It has been fixed now. Please try again.
That works. Thanks!
With that, I’ve managed to successfully update my firmware to 2.2.1 and my web app version to 2.4.1. (It turns out that I already had a DHCP reservation in place that I didn’t even remember creating.)
I did have to reconfigure my zone names and programs, but that isn’t really a surprise given the gap in versions.
