401 access denied error

Question

Since yesterday I'm having this error. I can't figure out what the problem is. I haven't changed anything. The only thing I can think about is that my free credit expired and Bing asked me to update my subscription which I already did.

{"error":{"code":"401","message":"Access denied due to invalid subscription key or wrong API endpoint. Make sure to provide a valid key for an active subscription and use a correct regional API endpoint for your resource."}}
