Client ID invalid when authorizing OAuth

Hi guys, we have problem with our Client ID, when we try to authorize the system show us following error message:
{
"error": "invalid_client",
"error_description": "The client id supplied is invalid"
}
Our Client ID is: 8f60745c6d69df7dbc5ee7a0f4483e19ee5bade873b4f2c5c26813e1c5b434b9
You can help us to check what happens?
Thanks!
