    --dns.propagation-wait value                                 By setting this flag, disables all the propagation checks of the TXT record and uses a wait duration instead. (default: 0s)
    --dns.resolvers value [ --dns.resolvers value ]              Set the resolvers to use for performing (recursive) CNAME resolving and apex domain determination. For DNS-01 challenge verification, the authoritative DNS server is queried directly. Supported: host:port. The default is to use the system resolvers, or Google's DNS resolvers if the system's cannot be determined.
    --http-timeout value                                         Set the HTTP timeout value to a specific value in seconds. (default: 0)
