Not a valid origin for the client from Google API Oauth

Question

I\'m receiving this error from Google API Oauth:

idpiframe_initialization_failed\", details: \"Not a valid origin for the client: http://127.0.0.…itel

Answer 1

It might be in case, while you are using same email id for creating client id and for sign-in through webpage

Answer 2

If it's all the same to you, try adding http://localhost:8887 to your authorized JavaScript origins instead. Had that error myself at some point and this fixed it. Know that you will have to use this URL for your request as well event though it translates to http://127.0.0.1:8887/.

Answer 3

I read on several places on the web people use to redo the creation of the credentials to get it to work.
So I did, I created a new credential for the same project and used my new user-id and it worked perfectly... Looks like the edition of the whitelist is a bit flacky...

Nb: I also used localhost instead of 127.0.0.1, IPs are not valid.

Answer 4

I just went through all of these solutions before realizing I was putting in

https://localhost:3000

and my dev server was serving up

http://localhost:3000

Stupid, I know, but someone else will probably make the same mistake and perhaps this comment will help them :)
