Hello, LacyKissinger.

I want to help you out with the Delivery Server Down issue, but I'd like to some more details about this. 

Just making sure we're on the same page, did you encounter this issue when sending out invoices or any specific forms? If possible, what's the complete error message when sending them out? Lastly, what specific steps did you take to try and fix this on your end? I'd like to know this so I can lay down the next steps and details.
