The quickest way to get around this is to create (or upgrade your project to enable Firebase) in the Firebase Console first; then connect your app through the Android Studio tool again.
This is a generic failure message so to help us investigate it would be great if you could provide the detailed error message from the Studio log. You can find this by going to 'Help > Show Log ...'.

I had this message as well. However, when I went to the Firebase console I noticed that one of my project variants got uploaded. So, I ignored the error message and continued connecting to Firebase. Every time I did this it uploaded one of my variants. When all of my variants were uploaded, the error message went away.

I also faced same issue. I tried everything. I have searched everything on google but did not got anything but finally I got a solution for this. Firstly go and simply update your android studio and plugin. After updating your android studio to latest version, every problem will get sort.
After doing the above step, if you are still facing the same issue then check, if you have already made three projects on google cloud platform i.e. firebase. If you have already made three then contact google to increase your free project quota on firebase. To do so, fill the below form, they will approve your request. form link - https://support.google.com/code/contact/project_quota_increase
When google will approve your request then your issue should get resolved
