Not able to fetch data from https://www.zohoapis.com/crm/v2/org when access token generated from https://accounts.zoho.eu/oauth/v2/token

Not able to fetch data from https://www.zohoapis.com/crm/v2/org when access token generated from https://accounts.zoho.eu/oauth/v2/token

We have a client id registered in https://accounts.zoho.com/developerconsole.
Now configured that client id Multi-DC enabled for EU.
So with the Client Secret for EU, we can generate the access token using following API.
https://accounts.zoho.eu/oauth/v2/token

But with this generated access token, when we are trying to fetch organization information using following API, it is giving message UNAUTHORIZED (HTTP ERROR CODE : 401)
https://www.zohoapis.com/crm/v2/org

But If we try to fetch the organization information using following API, it is working fine.
https://www.zohoapis.eu/crm/v2/org

Please help us in this regard.
Can we configure the client id as global client id so that same client id and secret works fine irrespective of domains for ZOHO rest APIs.
