I have Duplicati 184.108.40.206 Beta installed on a Mac that I recently upgraded from Catalina to Monterey. Duplicati was working fine before the upgrade, but I can’t open it since the upgrade.
I’m used to seeing a Duplicati icon in the Mac menu bar, but since the upgrade, it’s not there. If I open Duplicati from an icon, I get no response, and if I open the Duplicati UI from a bookmarked URL, http://localhost:8200/ngax/index.html#/ my browser returns a “connection refused” error for localhost:8200 .
I suspect that the upgrade to Monterey is causing a permissions issue somewhere, but it’s not obvious to me just where that might be. My initial inclination is to check the Privacy tab in Security & Privacy, but checks of the settings for both Full Disk Access and Files and Folders both show full access granted to Duplicati. A browser error of this sort implies the possibility of firewall, but I still get the error with the firewall temporarily turned off.
Any ideas of what else might need attention? Is this something that an uninstall/reinstall might fix?
