google webmaster

when i make a cname verification google says that it cannot able connect to the server

if your domain is new (day or two)
You need to have patience for DNS propagation cca. 2 days

after that even HTML file upload verification works

I doubt Google would say “cannot able connect to the server”, because Google is an American company and that sentence is not valid English.

What is the full error message presented by Google (not just your interpretation)?
