Running Pro 2015.  I am trying to email an e-invoice and I am unable to.  I keep getting the error "Server Connection Error.  Something went wrong. Try again to send an e-invoice.  Alternatively, you can choose to send a regular invoice without the "Pay Now" Link. <Send Regular Invoice> <Try Again>".  I started getting this error on an old computer so I moved my installation to a new computer, was able to send one e-invoice then started getting the error again.  I am able to send a regular invoice to email just fine.  Thank you for the help!
