Verifying website ownership

Hello, I am having trouble verifying the ownership of my website in the safe web system. I have followed the steps as described on the site. I have added the meta tag to my pages and attempted to verify multiple times. When that didn't work, I attempted the "Upload an HTML file" method which the system again, failed to verify. My website is sfmlab.com and the report page is here:
