Registration IP Address is duplicated for so many users

Hi @Chi_Duc, I am not sure about Azure servers, but usually the server’s IP as a user’s IP is shown in case on incorrect proxy settings. I mean Nginx settings. Try to add the lines from my post into your app.yml and rebuild. Anyway, this will break nothing, and you always can revert these changes any time.

I suppose your server may have dynamic IP, therefore some users have the same IP.
