Why doesn't browser-sync work on devices connected to the same Wi-Fi network?

Question

Browsers

Everything worked great before. A month later, the project launched with browser-sync does not load on any device, except for the laptop itself, where gulp itself and browser-sync actually work.
It gives the following error "Unable to access the site", "ERR_CONNECTION_REFUSED".
Do not know how to solve the problem?

Answer 1

Solved the problem very simply in gulpfile.js added any convenient name to the tunnel parameter
