The server on the laptop does not see what is the reason?

Question

Computer networks

There is a laptop and 2 PCs, everyone has win 10. Router zyxel viva all PCs are connected via cable. ISP static IP. All ports are open on the router, PC and laptop. Setting up an antivirus on a laptop is a complete copy of the PC. Essence of the question: I create a server on any PC, everyone sees it, including the laptop, both locally and not locally. As soon as I launch it on the laptop, no one sees it, not locally, not like in general, and even the laptop itself. The server files are all the same. Before that, the laptop had vin7 thought this was the reason, demolished and installed vin10, it did not help. What could be the reason?
