Firebaseui-web: Hostname match not found

[karimmorta]

"Hostname match not found". I have this error randomly
thrown at some configurations web and mobile. Can't find any tangible common specs.

Does it have something to do with SSL certificates ? my app being hosted on Heroku, the original domain name myapp.herokuapp.com does have a certificate and allow https, but my main domain myapp.com doesn't.

Make sure you whitelist myapp.herokuapp.com and myapp.com in the Firebase Console -> Authentication -> sign-in-method -> Authorized Domains. SSL certificates should not matter:
https://firebase.corp.google.com/u/0/project/$PROJECT_ID/authentication/providers

Thanks @bojeil-google, I actually just managed to fix the error, in fact by adding in the Authorized Domains www.myapp.com in addition to myapp.com, even though I expected the latter to handle both of them at first, www.myapp.com being a subdomain of myapp.com. (Automatic subdomain handling is suggested here https://support.google.com/firebase/answer/6400741)

@bojeil-google @karimmorta I have added my domain from heroku [project].herokuapp.com and it's not working.

Hey, I had been getting the auth/host-match-not-found error for some days and the problem was the following:

I had whitelisted the [email protected], but not the www.appname.com domain. The 'www' in front counts as a separate domain and has to be whitelisted exclusively.

Make sure to whitelist your domain both with and without 'www' in the front.

I have added both domains in my firebase console but still getting the hostname error if you could help
