TranslatePress Google API Error

Hi Support, Im having an error in the automatic translation section, it says I have a problem with my API key. When I try to validate it throws this 403 error:

{
? "error": {
? ? "code": 403,
? ? "message": "User Rate Limit Exceeded",
? ? "errors": [
? ? ? {
? ? ? ? "message": "User Rate Limit Exceeded",
? ? ? ? "domain": "usageLimits",
? ? ? ? "reason": "userRateLimitExceeded"
? ? ? }
? ? ]
? }
}

Would you please help me with some troubleshooting tips to get this work?

I checked in the google console and it seems we have not exceeded the usage limits, could you please give me a hint of where to verify the usage limit that this error is reffering?

We have used this pugin for a while and we have 3 languages already working on the site and now that we need to add another one, this is happening.
