Invalid Token with RestAPI but working with my existing project


I am continuously getting Invalid token on my any project. Even I created an new blank project and received token. Its not working. I checked my Auth many times, re-generated them as well and I am 100% sure my token is correct as my existing project is working perfectly with same token every time I refresh. Even tried with Apiary, got same result. Don’t know why my Auth-Token is only showing invalid.

There are only 3 servers - New York, Singapore and Frankfurt.
