We tried to verify your API key but it seems it is incorrect.

I’m using ACF Google font Selector version 3.0.1 with WordPress 1.6.1.
I’m aware there’s a similar topic (@cauzeneffeckt), but that problem seemed to resolve itself.

After adding a Google API key (settings), the following error appears:

`
“We tried to verify your API key but it seems it is incorrect. Make sure to copy-paste it from Google exactly.”
`

– I’ve tried multiple API keys (via console.developers.google.com > create credentials > API key), but none of them works.
– There are no restrictions on the API key
– Also I’ve tried to wait multiple days, without any effect.

Am I forgetting something, is there an error I’m not aware of?
Thanks!
