What is the name of the domain?
skinn.gr
What is the error message?
Your verification DNS TXT record was not found. You might need to wait a few minutes before Google sees your changes to the TXT records
What is the issue you’re encountering
I have added the DNS TXT record for google-site-verification in Cloudflare, but I am unable to verify my domain in Google Postmaster Tools. The DNS propagation seems to be delayed, and the TXT record visibility is not working properly. How can I fix this?
What steps have you taken to resolve the issue?
I have checked DNS propagation using multiple tools, cleared the Cloudflare cache, and waited for more than 48 hours, but the issue persists.
What feature, service or problem is this related to?

Welcome to the Cloudflare Community. 
Can you share the name you were asked to use for the TXT RR and the contents that Google is expecting to find in the record?
The TXT record for my domain “www.skinn.gr” in Google Postmaster Tools is correct, and I have already propagated the DNS changes for over 48 hours. However, I’m still unable to verify the record. Could you please clarify if there’s something specific that might be missing or wrong in the content of the TXT record?
Here’s the exact TXT record content provided:
google-site-verification=2qf14E8aIAhvoD6LvQg6vxRQqXpY5IWl2mb64tqAU
Any help or further guidance would be greatly appreciated!
I see that you have google-site-verification=r2q1fAE8aIAh0vD6LxVgQ6vxRQqXpY5IWI2mh64tqAU published at skinn.gr
However, you don’t have any TXT records published at www.skinn.gr. Do you have that record in your Cloudflare DNS in the dashboard? Can you show it to us?
Thank you for your reply.
I have already added the TXT record for google-site-verification for skinn.gr at Cloudflare. However, I also added this record under the www.skinn.gr subdomain as well. I have included the screenshots to show that the TXT record is correctly set. Despite waiting for more than 48 hours for the DNS propagation, the issue persists.
Would you be able to help with any other possible steps or insights on why the verification isn’t working yet?
That screenshot doesn’t appear to have made it and you still don’t have a TXT record published. Can you try to upload your screenshot again?
