Miraweb usage on other device?

What I am testing is only the "Miraweb Overview.maxpat" patch.

In my case it seems that Miraweb works perfectly fine on the same device where Max is running, that is, it opens my browser and mirrors my max window. But I cannot get it work on another device by simply typing the address in the browser (they both connect to the same wifi).

I wonder if it is related to the network and firewall settings. How to resolve this?
