Protonvpn on android tv show: "no connect ip: unknown" and don't has anything else

I am trying to work on building protonvpn on my android tv set (panasonic). But it seems cannot be used. While opened up smooothly, the screen only shows two lines of text on the top of the screen: “no connect ip: unknown”. Rest of the content is just a void of blackness. I changed my tv’s ip to static but it still doesn’t make a change. And its icon isn’ showed up as other apks (only showed with name). What should I do?

The network options or compatibility may not be working right. Consider restarting ProtonVPN and making sure you have the most recent version that works with Android TV. Check again to make sure that your TV’s DNS settings are correct, or try connecting to a different network for a short time to rule out problems that are specifically related to that network.
