Connection between Android e Windows devices doesn't works

Hi everyone,
assuming that I do not know if is allowed a connection between different devices with the same Zero Tier One VPN network, I have a problem with connection between devices smartphone/tablet Android and PC Windows.
I have a PC used as server and I generated a link associated at web page and between PC, within network zero tier one, using the browsers the link works properly.
After installing Zero Tier One on smartphone device and added/enabled the network and enabled the app, unfortunately the link doesn’t works: the error that I display on Chrome (smartphone) is ERR_NAME_NOT_RESOLVED.
I tried to ping the IP Address (smartphone) via command prompt on Windows (where the server is installed) and it works properly!
Please could you tell me if exist a procedure to solve the problem?

Many thanks in advance.
