On your android, download this app:

https://play.google.com/store/apps/details?id=dns.hosts.server.change

set a dns of your choice and create a VPN.

With “Proxy,VPN,TOR” and “Literal IP Addresses” disabled, pcwrt can’t establish a connection.

Try: Just send a simple whatsapp message and you will se that pcwrt can’t send it, or, sometimes, will send it after 15, 20 minutes.

With the data mobile, i have no problem. I tested it on Android 9.
