There are many reasons, you should be more specific
for example in the config.xml you must have this tag and this one . In the index.html if you already have an updated version and you have the whitelist plugin should have something like this

On the other hand if you already have the above can include a navigation plugin like this org.apache.cordova.InAppBrowser. An example of this plugin is (‘my’, ‘_system’, ‘enableViewportScale = yes’, ‘location = no’);
