Error: Quota Error: User Rate Limit Exceeded.

I love this plugin and have been using it for years now!

I keep getting Error: Quota Error: User Rate Limit Exceeded and all my stats revert to 0. I have hidden the stats for now on my site.

But when I check my API – it says I am nowhere near reaching my quota:

Free quota
50,000 requests/day
Remaining
46,801 requests/day
93.6% of total
Per-user limit
10 requests/second/user

And I actually have less traffic this week than I did last week, so it doesn’t make sense.

I have tried everything, including resetting the keys, creating new credentials, clearing cache, sometimes it works for a little but then this problem always comes back. I’ve never had this problem before. Please help!
