Most of the assets are not deleting while trying to remove, it shows Network Error? Any help/leads?

[Risikanta Pradhan]

I have more than 2000 assets in my object schema, which includes many duplicate assets.
I am trying removing them manually one by one as well as through the bulk Delete method using the Delete button, but when I try to do so, it shows, 

"We couldn’t delete your objects.

Please check your network and try again" - ERROR. (In attachment)

P.S. - I have checked my network strength it is quiet good.
