Error while trying to create a certificate, tried with multiple domains - [Solved]

Help

I tried to create some certificates and I couldn't with any domain, they are all on Cloudflare without active proxy.

My domain is: tt.t4l35.host, tt.t4l35.ml, error.t4l35.pp.ua, tt.t4l35.pp.ua

I ran this command: sudo certbot certonly --standalone --preferred-challenges http --agree-tos --email talesam@gmail.com -d error.t4l35.pp.ua (The command is the same, just change the domain at the end.)

It produced this output: (is the same output for all domains)
