[SR-Users] Presence not notifying?

[Mark Boyce]

Hi Again

Ok, something odd happing here.  Notifies have suddenly started arriving on the phone.  Maybe something has timed out and started working. Going to reset everything and see what happens.

So looks like the core issue might be the AUTH route challenging locally generated PUBLISH messages.

Best regards
Mark

If I patch AUTH route to allow through anything with the servers source IP (A bit dangerous as someone could faking IP source on UDP. is there a better way?) the proxy_challenge no longer gets sent and I see what I think is it trying to send a notify to the watchers phone;
