X-facebook-platform authentication failed: again

Hi,

First off, sorry to bring up this question about this error message:

SASL authentication X-FACEBOOK-PLATFORM failed: not-authorized

I am building a simple facebook chat client using JAVA, smack and X-FACEBOOK-PLATFORM for authentication for school project.

I have a valid access token through the facebook-documented client side flow. I have the xmpp_permissions obtained.

I found the custom X-FACEBOOK-PLATFORM elsewhere on this forums and stackoverflow. Trying to reuse it, but getting the above said error.

Here is the class and the code.

I searched, but found mostly old post from 2012 and also with no working solutions for me. Whatever minor changes were suggested I tried them. But to no use.

Any kind of help is appreciated. Also, very much a java and smack newbie here. So even the basic errors I might have done, please do point out and guide me. Thanks in advance.

No, 5223 is obsolete SSL port. Openfire uses 5222 for both unencrypted and encrypted connections.

i just realized that on another post! Retract my previous post!

But I am using 5222. Did not understand.

disregard, i thought you needed to use a different port, but i was wrong.
