Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: kflix.co.uk
I have my domain setup with traefik as the reverse proxy and using cloudflare as the DNS provider with proxy. Traefik usually auto updates the LE certs 30 days before they are due to expired but this time it has failed. All previous attempts to renew the certificates have worked perfectly fine and no changes have been made to the traefik or cloudlfare configurations since the last certificate renewal.
I'm relatively new to all of this and have no idea what the error means or how to solve it. Any help would be greatly appreciated.
Traefik logs show the following error:
"time="2020-12-01T22:36:16Z" level=error msg="Error renewing certificate from LE: {kflix.co.uk }, acme: Error -> One or more domains had a problem:\n[kflix.co.uk] [kflix.co.uk] acme: error presenting token: cloudflare: unexpected response code 'SERVFAIL' for _acme-challenge.kflix.co.uk.\n"

My web server is (include version): Traefik installed via docker
The operating system my web server runs on is (include version): Ubuntu 18.04.
