Unable to install on Mac; unable to download patch files, [30413][25008][10009]

Have tried 4 times now to install (new purchase, new computer). I am running macOS Catalina 10.15.4. I have no other programs running in the background.
Each time I get the following error message:
Unable to download patch files.
[30413][25008][10009]


Recently found a forum that said to delete the folder "/Library/Application Support/FINAL FANTASY XIV/" which I did without success. I would prefer not to install an appcleaner app nor do I want to have to uninstall the entire thing to try again.

Thanks!:(:(:(:(

Good morning and thank you for visiting the Final Fantasy XIV Technical Support Forums.

Please try the following troubleshooting steps:

- Ensure the latest version of Safari is installed on your Mac (even if you don't use Safari.)
- After updating, open Safari browser and make sure that all Browser History and Cookies/Web Data have been deleted.
- Please also make sure that "Cookies" are accepted and not being filtered.

Once these options have been adjusted, please run the Apple Update program to check that all firmware is up-to-date on you Mac OS. Once this process is complete, please re-launch the FINAL FANTASY XIV application.

-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Still got the same error with those ports open.
