2501928 - SAP NF-e Troubleshooting Guide for Communication Errors

Your SAP NFe system is facing communication errors with PI or even SEFAZ, errors like, "unable to create a socket", communication error, connection reset, ... are shown in the SXI_monitor while attempting to check XML communication messages.

**IMPORTANT**

UPDATED: 10 Jun. 2023.

Legal Change Minas Gerais (MG) State. As of 08 Jun. 2023 following the "Manual do Contribuinte" another standard other than SOAP version 1.2 will no longer be accepted by Sefaz MG. 
There is no need to proactively change the communication channels, if you already did it, please revert the changes.
SOAP 1.2 is already being used for a long time and is filled in via code, it seems there is an error in the title in the label only that shows SOAP 1.1, but nothing to worry about.
If you keep the communication channels with the standard customizing you will not face issues to approve the Notas Fiscais with the MG government.
