Hi,

Greetings. I executed the sample program provided by Refinitiv world check id. The program was successful and working fine from my lab which is based in other location. I'm tried to execute the same program in my local environment, I'm always receiving the 401 error. I used same apikey and secret key.

I do not see any proxy issue as well with local system. is there anything to do with the timezone.

I tried to execute the sample request through postman. I received same error over postman as well. I'm not sure why the authorization failed with the same key and secret.

Please help me to resolve this issue. Please let me know if you want me to share the entire program.
