This issue might be caused by many reasons, You need to make sure that the document you sign have the same exact values of the document you are sending to ETA API.

Also, if your invoice includes any Arabic letters this issue will always happen until you update the https://github.com/mrkindy/EgyptianEInvoice library on your server. I have pushed a PR mrkindy/EgyptianEInvoice#6 that fixes the Arabic characters issue not begin sent correctly to ETA API.
