??? list "Supported Providers"
Here is a list of supported `providers`, that can automate the DNS verification, along with the required environment variables and their [wildcard & root domain support](#wildcard-domains).
Do not hesitate to complete it.

!!! note "Double Wildcard Certificates"
It is not possible to request a double wildcard certificate for a domain (for example `*.*.local.com`).
@ -239,7 +247,7 @@ Thus, the wildcard domain has to be defined as a main domain.
Most likely the root domain should receive a certificate too, so it needs to be specified as SAN and 2 `DNS-01` challenges are executed.
In this case the generated DNS TXT record for both domains is the same.
Even though this behavior is [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) compliant, it can lead to problems as all DNS providers keep DNS records cached for a given time (TTL) and this TTL can be greater than the challenge timeout making the `DNS-01` challenge fail.
The Traefik ACME client library [LEGO](https://github.com/xenolf/lego) supports some but not all DNS providers to work around this issue.
The Traefik ACME client library [LEGO](https://github.com/go-acme/lego) supports some but not all DNS providers to work around this issue.
The [Supported `provider` table](#dnschallenge) indicates if they allow generating certificates for a wildcard domain and its root domain.
