Safari 16.1 (macOS Ventura) cannot access Dropbox files

[GMart1120]

Safari cannot open the page.The error is: "The operation couldn't be completed.  (kCFErrorDomainCFNetwork error 1.)" (kCFErrorDomainCFNetwork:1)

Dropbox recently moved itself to "a safer location", i.e., ~/Library/CloudStorage/Dropbox.  Everything was fine.  Afterward, I upgraded macOS to 13.0 (Ventura).  Safari is now ver 16.1 and cannot open html files stored in Dropbox.  All other apps appear to be quite happy with cloud versions of Dropbox files, including Chrome, TextEdit, macVim, Terminal, etc.  Probably something minor, but not sure what.

This is the most recent version of both

@Hannah - I think Safari is up to date -- Version 16.1 (18614.2.9.1.12).  macOS is 13.0 (22A380).

Same problem after Dropbox moved this week my files to ~/Library/CloudStorage/Dropbox. Use most recent Mac Ventura version. Safari Versie 16.1 (18614.2.9.1.12). 

Don't see any solution yet. Anything coming?

Same problem here. Ventura 13.1; Safari 16.2 (18614.3.7.1.5); Dropbox v163.4.5456.
Static HTML file stored in Dropbox.
Same effect with file as default access or set to "Make available offline"

File _is_ accessible via Chrome 108.0.5359.124, and other apps such as BBEdit.

Interestingly, when I tried to open with Firefox (104.0.2), it requested access to files managed by Dropbox, and then opened the file...using the _old_ link. Firefox appears to be following the newly-created alias into the new CloudStorage directory...and Chrome seems to be able to do that too. Safari will not do this.

I suppose it's also worth noting that Safari _will_ open a copy of the same file located in iCloud Drive.

There doesn't appear to be any movement on this issue.  Alternatively, is there a way to move the Dropbox directory out of ~/Library/CloudStorage/, back to "normal space"?  I'd like to resume using Dropbox, but the current situation is a showstopper.

Found a solution. You need to give Safari "Full disk access" via System Settings (Privacy tab in Privacy & Security part)

[KePar]

Correct. Works. But is it safe? normally an app asks for permission for the part of your drive it needs.

[DCSkipper]

Don't see Safari listed under full disk access.  Do I need to add it manually?

[mrkva]

Yes, add it manually via the "+" button. Not sure about the safety of this method, it is up to Dropbox/Apple to say...

[KePar]

Yes. Which is what I do not trust. Normally an application asks for permission and, if affirmed, appears in Files and Maps list (you cannot enter anything there). Hence it stays for me a flaw in the Mac/Dropbox design, which Dropbox should address.
