DNS query failure

Today I updated v84 latest. But I got this error: [root@tr7 ~]# /usr/local/cpanel/cpkeyclt updating cPanel license...warn [cpkeyclt] DNS query failure (auth.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79. warn [cpkeyclt] DNS query failure (auth2.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79. warn [cpkeyclt] DNS query failure (auth10.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79. warn [cpkeyclt] DNS query failure (auth5.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79. warn [cpkeyclt] DNS query failure (auth7.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79. warn [cpkeyclt] DNS query failure (auth9.cpanel.net/A): Can't use an undefined value as a subroutine reference at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/x86_64-linux-64int/DNS/Unbound/AsyncQuery.pm line 79.
