verification not working in smart crawl

I'm getting the following error in smart crawl when i put the google verification meta tag in the system:

Verification failed for using the Meta tag method (less than a minute ago). Your meta tag is not formatted correctly. To avoid errors, copy and paste the contents of the meta tag directly from the instructions.

Tag that I was using:
<meta name="google-site-verification" content="4QYZ1UEnFWTs5GhqBKO_xZ7ALVf7aJ04STElSe85zqA" />
