Not able to access a specific site collection from a farm server

Hello there,

I am having server 1 and server 2 in SharePoint farm.

I created a site collection and mapped to a new content database using powershell in server 1.

Now when I access the lists under that site collection using object model from server 1 applications it is working fine. But when I access the same site collection lists from server 2 then I am getting 'Object reference error'

To be noted down here is I am facing this issue for the newly created site collection but the old site collections are accessible from both the servers.

Please help in identifying what I am doing wrong.

Thanks.

Regards,
