Orbi Satellite Firmware update fail

When I go to the Firmware update page on my Orbi RBR50, it shows that the router is up-to-date.  2.1.1.16.

The satellte RBS50 shows firmware 2.0.0.74 and after awhile, shows update failed.

I tried manual update of the satellite, but when I click update from the manual page, it comes up with a login for the satellite.  I enter the same info as my router, but it says "Access to this resource is denied, your client has not supplied the correct authentication".

I have tried resyncing.  no effect.

I would appreciate any suggestions so I can get my satellite to the same FW version as the router.

Thanks.
