Need Help to Verify My Domain and Activating My Subdomain

Hello, I am facing two problems. Can anyone help me to fix my issue? 1. I would like to verify my domain for G-Suit. I have added TXT value in cpanel. But still Google is unable to verify the domain. -Suit.png">79553 2. I have created a subdomain. the subdomain is not working. It shows "DNS_PROBE_FINISHED_NXDOMAIN" this error. I have also added a "A" type record for the subdomain. But its not working. I am using shared hosting from HostGator. So, can you suggest me any solution to these problems? Looking forward to your assistance. Thanks in advance. :)
