Hi everyone!

I'm having trouble verifying my XMPP identity using the proof utility kindly provided by Yarmo. As soon as I sucessfully login I get the following message:

XAPU Error

At first, I thought this was an issue with the server that was hosting my account (pesader@jabber.calyxinstitute.org), so I created another account on a more popular server (pesader@jappix.com). Unfortunately, I got the same error on both. Is there some account setting I need to toggle to get it working?

Thanks in advance!
