I was running on emulator android and it throws this error
0 820714 error No Content-Security-Policy meta tag found. Please add one when using the cordova-plugin-whitelist plugin.
I tried to find solution for adding this line below in index.html
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
...
or below for test in config.xml
<allow-navigation href="http://*/*" />
both does not seems to help.
