Mac 10.15.5 and v1.3.0 web - not opening

I just upgraded to mac v10.15.5 and now duplicacy will not open. I click on the icon and nothing happens. I have rertarted and re-downloaded the program. No luck. Any suggestions?

You can start the web GUI from Terminal by entering this command:

/Applications/Duplicacy\ Web\ Edition.app/Contents/MacOS/duplicacy_web_osx_x64 

This should give you more information why it is not starting.

Thank you! I had changed my ip address from 127.0.0.1 and I was on a different network. I edited settings.json and it is working.

Appreciate the quick response.
