Changing the DNS server solved the problem

@pparent : Thank you so much!!! This was the solution Important for me in efl was not only to change the title, but also the name of the window, that means instead of only $win = pEFL::Elm::Win->util_standard_add("main", "pefl.maxperl"); also $win = pEFL::Elm::Win->util_standard_add("pefl.maxperl", "pefl.maxperl");
