This did indeed fix the checking for addon updates under the tool menu

of the NVDA UI. Checking for a NVDA update under the help menu still
causes a error message.

First, thank you for reporting add-on update error messages. The issue
was traced to NVDA not looking for the correct SSL error, possibly
caused by expired root certificate from Let’s Encrypt. As a result,
Add-on Updater 21.10 was just released (manual download for now):
IMPORTANT: Add-on Updater 21.10 is a MANDATORY update to anyone using
NVDA 2021.1 or later. I cannot backport this to earlier NVDA releases as
the add-on uses features introduced in NVDA 2021.1.
In addition to fixing SSL certificate verification error, Add-on Updater
21.10 makes it possible to check for add-on updates after you perform a
clean Windows installation without connecting to the Internet and then
go online afterwards. This change comes from upcoming NVDA 2021.3 (alpha
snapshots at the moment).
I advise applying this update as soon as possible – for now after
installing Add-on Updater 21.10, ignore an offer from Add-on Updater to
install Add-on Updater 21.09 – I will update this thread once Add-on
Updater 21.10 is indeed offered.
