The API Access keys are not working for me

Hi Team,
Post generating the access keys when trying to utilize the same on portal ,its not working for me . Please assist to authenticate me and enable my access .

You can now go into your OpenAI account API key management and delete the key, so it is not abused by plugging a key into someone else’s nonfunctional site that could be logging and stealing them…and sharing most of the key in your screenshot.
