Uploading logs to Mac

Having trouble uploading my logbooks from HAMRs on my Mac. Keep getting error message stating they are being blocked. Turned off firewall to no success. Suggestions?

Post a screenshot of the error message and someone may have some insights. Is the error from the computer or from POTA.app? BTW- a Mac screenshot is taken when you hold down Command-Shift and press the number 3! It’ll save to your desktop.
