Problems generating certs "cloudflare: failed to create TXT record: Record already exists. (81057)"

Traefik Traefik v2

I get this error, any idea why? I'm totally stuck and I have tried everything

time="2023-05-24T19:28:40+02:00" level=error msg="Unable to obtain ACME certificate for domains "whatever.com.es,.whatever.com.es"" ACME CA="https://acme-v02.api.letsencrypt.org/directory" error="unable to generate a certificate for the domains [whatever.com.es .whatever.com.es]: error: one or more domains had a problem:\n[.whatever.com.es] [.whatever.com.es] acme: error presenting token: cloudflare: failed to create TXT record: Record already exists. (81057)\n[whatever.com.es] [whatever.com.es] acme: error presenting token: cloudflare: failed to create TXT record: Record already exists. (81057)\n" providerName=letsencrypt.acme routerName=homeassistant@file rule="Host(ha.whatever.com.es)"

I was using previously SWAG(nginx) so now I'm generating the certs with traefik.

Have you tried removing all (now) unused TXT records?

It was a problem with the firewall and probably something else, I fixed it deleting the acme.json, the txt and allowing DNS connectivity to cloudflare.
