Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Janet,
Thank you for choosing Microsoft Community. I will help you in providing the steps to determine the cause and fix the issue.
One of the common reasons for this error message is if the firewall or 3 party software on the computer is conflicting.
Let us disable the Firewall temporarily. Refer the following link to disable Firewall:

Restart the computer and check if you can upload the webpage and publish through FTP.
If that does not work, restart the computer in clean boot and check. Refer the following link on How to restart the computer in Clean Boot:

Note: Ensure the computer is restarted to normal mode after performing the necessary steps.
I hope the steps provided fixes the issue. If the issue persists, reply and I will be happy to help you further.
Thank You.
