It seems it’s a similar issue to https://launchpad.net/bugs/1548020.
When clicking the download button in the nextcloud UI, a request for
the file with a secret parameter is issued to the web server, and gets
a 200 response (OK). Oxide then cancels that request and passes the
parameters to the Ubuntu Download Manager, which re-issues the same
request to initiate the actual download. The second request is denied
(I’ve seen 401s and 503s), most probably because the secret is a
one-time token that has already been used:

I will update the bug report to include the nextcloud use case, and
will bump its importance, although as things stand we don’t have a
clear solution to it.

Cheers,
