New issue so thought I would create a new question
I am getting above error. I have followed the post about how to fix.
I can telnet to the IP not the domain. So I tried putting the domain in the ROOT.xml, restarted and it didn't work, so then I changed it back to domain and added an entry for the IP to the domain but still nothing works. I also changed to push messaging and it still will not send a message or update my devices. Everything else works.
Do I need to reimage all the phones when I change to Long polling?
