Signature failed when delivering version document invoice.

Hello, dear, I'm glad to answer your question. A: When the format document invoice was delivered, the signature failed. 1584 network to issue electronic invoices. During the online uploading process, the tax digital certificate failed to add a digital signature to the electronic invoice. The signature failed due to the docking failure of the tax bureau system. You can manually sign, open the invoicing system-invoice query-query by invoice number-close unsigned invoices-repair invoices-and retry invoice signing. There are two specific reasons: 1. After invoicing, the digital tax certificate will be invalid in the process of adding digital signature to the electronic invoice. Second, the failure of the inspection system of the tax bureau will also lead to the failure of the inspection.
