Sim800L Can’t Publish MQTT Package to Server

Hello Ravi. Thanks for your tutorial.
I created a TCP Client using Hercules software and connected to the IOT server and was able to publish data to the server using an Excel file.
I did the same thing with the sim800l and connected to the server and sent the same previous pack to the sim800l, I also received the SEND OK answer, but nothing was received on the server.
Please guide me. Do I have to change the pack?
