it seems that webview can not display pages from Node-RED server (v0.19.4). https://nodered.org/
it looks ok in chrome browser but at webview it is just white.
Same here. Looks like it uses a long polling socket that doesn't work with WebView. Maybe you can configure the server to switch to regular WebSockets.
