Error Message: "Failure to Start the Upload"
Hi:
All of a sudden this morning, Dreamweaver fails at uploading files that had been uploaded during the last three days. Here's a screenshot of the error message I got that I've never seen before. It shows that one file that had previously been uploaded, wouldn't upload today . . .

So, I quit DW and my other open apps and restarted my iMac (running Mojave) hoping that would reactivate DW appropriately. It didn't.
Then I selected a random group of files and attempted to put/upload them. For no apparent reason, the majority of files failed to upload. None are particularly large. Each error message suggests that there was "a failure to start the upload."

Is this a DW problem or a remote server problem? If it's a DW problem, what must I do to get DW to cooperate with a simple directive to put files (new and existing) to the remote server?
Please help me regain DW's functionality so I can update my client's page. Thank you very much.
Warren
