The keyword tracker used to work for me for many years until this week: I am getting this error message: The following error occurred: The calling IP address 45.40.164.137 does not match the IP restrictions configured on the API key. Please use the API Console to update your key restrictions. () Don't quite understand this- what exactly should I do?
You would need to log into your Google API Console. It sounds to me like you set IP restrictions on your API key (probably best to remove them or at least change them to the correct IP block you are using if you want to enforce IP restrictions).
