Error (4800004) authorizing web app

Question

I was debugging my app in my personal Google play services account but the company I am working on has already got their Google play services account so I changed and DELETED (deleting api credentials and unpublished it) the game. I have managed to register a new android app but when I try to register a web app I get the error #4800004 (An unexpected error has occurred. Try again later). What should I do?

Answer 1

It can take approx 7 days for your old package to be removed. You will not be able to add a new one until that happens.

Your options:

• Wait 7 days and try again.
• Rename your package.

Alternately: You cannot have two apps with the same package details. Are your two apps conflicting with each other?

Answer 2

From the github post, it was mentioned that you maybe re-registering an app with the same package name. You can check if your project was already registered in the console. Projects that you have deleted will take effect after the 7th day.
