access to fetch at '<Authserverurl>/as/token.oauth2' from origin '<domain>' has been blocked by cors policy

[VijayaSaiRam]

Hi team, I am getting the following error. access to fetch at '<Authserverurl>/as/token.oauth2' from origin '' has been blocked by cors policy: no 'access-control-allow-origin' header is present on the requested resource. if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with cors disabled.

Could you please let me know how to solve this issue

Thank you inadvance
