@tyxchen Do you know about how long it took for your records to finally proapgate? I’m experiencing the same thing, I think it’s been close to an hour for me. I was originally trying to update some certificates with certbot, but unable to use Cloudflare for authentication because it can never read the TXT records that it creates. I’ve been testing adding some A records too but am not getting a response when I try to query them with dig.
Also, it seems that this problem has been going on for me at least since Thursday, judging by certbot logs. When It tries to do the verification, I can see the TXT verification records in the web interface, but both certbot and dig fail to find them.
