Incorrect TXT record when creating SSL certificate

[GeorgeRG]

Hello everyone,
I am kinda new to the whole TrueNAS thing so bear with me, I might be missing something really simple.
I am trying to get an SSL certificate to use on traefik. I followed every guide I could possibly find and all of them recommended Cloudflare so I went ahead and created an account. Everything works fine with the setup until the time comes to actually create the certificate. I press the button, wait a bit and a big fat error pops up saying that the TXT record found was incorrect.

Reading throw the error I figured that the record was actually missing completely. I could only think of 2 possible problems:

• The port forwarding on the router
• The DNS records for the domain

I checked both of them but everything seems fine. There is nothing else I can think of so i reach out to you.

Thank you in advance.

Below you can find the whole error:

Code:
