Getting denied(invalid token) for ghcr.io for valid PATs

Hello,
Since, this morning I am unable to do docker login to ghcr.io using my existing as well as newly created PATs. When I ran curl -v -u $USER:$CR_TOKEN https://ghcr.io/v2/ in my local, it returns 403 with -
{“errors”:[{“code”:“DENIED”,“message”:“invalid token”}]}

Any help appreciated.
