Filling Server IP Whitelist in facebook app

[mstdmstdd 0]

Hello


I try to register my app in facebook and I entered my Domanin Manager as https://www.votes.my-demo-apps.tk/:

I try to fill fields : Server IP Whitelist and Update Settings IP Whitelist (I suppose that I need them both)

But I failed to save these options "
