Upgrading Nextcloud

Hi all. I get regular pop ups telling me Nextcloud can be upgraded. Trying to do this in Forris however does not work. The following notification is shown.

Error from 2020/02/02 21:02:06

Updater failed:

runtime: [string “requests”]:395: [string “utils”]:429: Unable to finish URI (https://repo.turris.cz/hbs/mox/lists/base.lua): Download failed

Similarly when I use the updater tab in Forris I get a blank page.
Can this be done from the command line? Any suggestions appreciated.
Sometimes I am confused about whether I am trying to update Nextcloud or Turris or both. Using Turris Mox with Modules A + F
