Unable to get a backup to work in the snapshot. “Timeout error”

Unable to get a backup to work in the snapshot. “Timeout error”. I would prefer to use the Dropbox connection that is set up. Local or Dropbox either option will result in the same error.

And with managed backup getting the below error:
“Description: Too much time has passed without sending any data for document.”
