HTTPS works but HTTP connection will return a -300 code

Former Member over 6 years ago

I started an Widget development, which contact internet for some information through HTTP with some authentication headers in GET method.

The code works fine in Simulator in developer SDK, but it doesn't in real device (my Vivoactive 3 music version) it shows an error code of -300.

However, it is working as well when it is using HTTPS protocol.

Did anyone meet the same issue?

Is it a bug in real devices?

With Android, you can only use http to access localhost

I am accessing to remote host directly in the app, the URL to visit is a domain name to a remote server.

To be specified,

I use Communications.makeWebRequest('http://datamall2.mytransport.sg/ltaodataservice/BusArrivalv2'...) etc.

Or are you telling me because it is still using bluetooth through "Gamin Connect" (which is worked as a proxy in Android), it still count as visiting localhost?

You can only use http if you are hitting a web service on your phone ("localhost"). If you are going through your phone to something else, you must use https. In your case, it's got to be https.

in the sim, make sure "Settings>Use Device HTTPS Requiremnents" is checked for testing
