Question Re-issue Let's Encrypt Certificate

[Aymania]

Greetings,

I am extremely new to Plesk.

I have a domain managed by Plesk with Let's Encrypt SSL, I want to include the Wildcard SSL for subdomains as it's now supporting only the main domain. I went through the Re-Issue process and I have selected all options. Plesk then created the TXT record and I can see it under the DNS settings. However, when I check the domain TXT record (I am using TXT lookup from mxtoolbox.com) it returns nothing. I assumed it will take time to reflect the update but unfortunately, it didn't work even I wait for more than an hour.

I have tried deploying that on another domain I have in Plesk but DNS managed by Godaddy and it went all perfect in few minutes.

Any Idea?

Thanks
