I was running some FireBase tests and suddenly I realized Firebase was not working anymore when using mobile data from Chile. At the beginning I thought the problem was my app so I tried to open a Firebase official example but I had no luck (office-mover-demo example). This is what I tried:

I connected the phone to my home wifi connection and FireBase works :) I shared the phone’s internet connection to my computer and it did not work :( . This is the error y receive.

I emailed Firebase support and they sill don´t have an answer to this strange situation. I asked people from The Netherlands and Mexico City to try and realized the problem was only happening in Chile :o . It’s like FIrebase URLS (http://firebase.com , firebaseapp.com ) are not reachable from Chile using mobile data plans! Does anybody have any clue ?IMAGE OF THE JAVASCRIPT CONSOLE OUTPUT

  • *firebaser here* It seems your mobile operator is blocking traffic to firebaseio.com. There is not much Firebase support nor the community of developers here on Stack Overflow can do to help with that. – Frank van Puffelen Jun 22 '16 at 17:11
  • Hi Frank, we tested it out with 5 different mobile providers. I don´t think all companies have any reason to block Firebase. – Juan Andres Jun 22 '16 at 21:44
  • @JuanAndres I also have the same problem. Do you already fix it? It was your provider? In my case I'm using WOM. – mafiu Jun 27 '17 at 02:18

I had same problem in egypt/vodafone 3g both in iOS and web too, for now am using VPN apps, once I turn on vpn firebase DB starts working :D :D

looks like it has to do with web sockets.
