I do find that the eagle is "touchy" when adding a provider.

• Sometimes it works right off, other times I had to delete the entry, confirm it was deleted, go back to the home page and start again.
• Mine also only took the IP address not the hostname. ie. 10.0.0.239
  
• It won't send to a SSL https server with self-signed certificate. This is if you deploy in your own app server.
• Give it 30-60 seconds.
  

touchy, but once it is added... it is saved.
