Can't update or install the Dropbox application on Fedora 43 Plasma

Application Affected
Dropbox
Device
custom desktop with ASUS motherboard AND Lenovo X1 Carbo Laptop
Operating System/Browser (if using the web)
Fedora 43 Plasma and Firefox (both systems)
Dropbox Version
Dropbox command-line interface version: 2025.05.20

I have been flawlessly running Dropbox on my Fedora desktop PC under KDE Plasma for 20 months. I installed it by downloading and running the RPM from this page: https://www.dropbox.com/install-linux

My system-wide software updates using DNF have been failing for several days with the following error:

[1/1] nautilus-dropbox-0:2025.05.20-1.fc43.x86_64                100% |  48.0   B/s |  15.0   B |  00m00s

Failed to download packages
 Librepo error: Cannot download x86_64/nautilus-dropbox-2025.05.20-1.fc43.x86_64.rpm: All mirrors were tried

I made the rash decision to uninstall Dropbox on my desktop rather than run DNF with the repo disabled. I then attempted to re-install using the downloaded RPM. The RPM installs fine and when run, it prompts me to install the daemon. I get the following error:

"Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set your http_proxy environmental variable."

I do not have any proxy and I'm not running a VPN. I can log in to Dropbox in my default browser (Firefox) with no problems.

When I try to update via the CLI, I get the following error:

[Errno 13] Permission denied: '/home/joe/.dropbox-dist/VERSION'

/usr/bin/dropbox:321: PyGTKDeprecationWarning: The keyword(s) "type, message_format" have been deprecated in favor of "message_type, text" respectively. See: https://wiki.gnome.org/Projects/PyGObject/InitializerDeprecations

I have installed the flatpak from https://flathub.org/en/apps/com.dropbox.Client for now, but it's an old version I would rather run your official version. I did not uninstall on my laptop. On there, I am disabling the repo for DNF updates. If I do not disable it, I get the same 404 error for the repository.
