traefik level=error msg="Unable to obtain ACME certificate for domains \"example.domain.com\": cannot get ACME client get directory at 'https://acme-v02.api.letsencrypt.org/directory': Get \"https://acme-v02.api.letsencrypt.org/directory\": dial tcp: lookup acme-v02.api.letsencrypt.org on 127.0.0.11:53: read udp 127.0.0.1:40126->127.0.0.11:53: i/o timeout" rule="Host(`example.domain.com`)" providerName=letsencrypt.acme routerName=traefik-secure@docker

Anyone could help me, please?

I did iptables -F and still problem persist, so it is not firewall.

Hello @Gfatarep44

Looks like a local issue for your container/docker it cannot lookup the domain name in the docker dns provider.

Possibly you can resolve this with dns options

Hello,

Thanks for the reply.

My /etc/resolv.conf file contains this:
nameserver 8.8.8.8
nameserver 8.8.4.4

What else should I do?
