Cannot login Yi Home, says “invalid data format, please try later”

I was unable to pair my camera so I reinstalled the app to see if that helps. After reinstallation, I was no longer able to login even though the username and passwords are correct. Does anyone have the same issue?

Thanks! Never mind, it works now. Seems that there was a temporary network issue on the server side. Now I can login and add camera without any issue.
