Google says that its Chrome browser will soon block internet websites from querying and interacting with devices and servers located inside local private networks, citing security reasons and past abuse from malware operations. From a report:
The change will take place through the implementation of a new W3C specification called Private Network Access (PNA) that will be rolled out in the first half of the year. The new PNA specification adds a mechanism inside the Chrome browser through which internet sites can ask systems inside local networks for permission before establishing a connection. If local devices, such as servers or routers fail to respond, internet websites will be blocked from connecting.
