I have a own ACME what was working for a half year. Now if the script tries to validate the domain every thing looks good, but the date returned by Letsencrypt is the same date it already had, (3 days left.) It looks like every thing is in order but the the date is not updated.
This is the resonse of the latest 2 calls combined in one:
Array ( [identifier] => Array ( [type] => dns [value] => stucadoorhilversum.nl ) [status] => valid [expires] => 2017-01-12T01:59:03Z [challenges] => Array (  => Array ( [type] => dns-01 [status] => pending [uri] => https://acme-v01.api.letsencrypt.org/acme/challenge/vkK3qgkWNpDKoRYv0z95on49ZNKbQEfrx5h-vyu1iLg/339693023 [token] => khCjRaNgPQbBBYpw0bTXbwjJNBezC2IPZeQ5-fKwtlg )  => Array ( [type] => tls-sni-01 [status] => pending [uri] => https://acme-v01.api.letsencrypt.org/acme/challenge/vkK3qgkWNpDKoRYv0z95on49ZNKbQEfrx5h-vyu1iLg/339693024 [token] => XfSD_grmf9sNmeJPNtioWFdIe_hvEDNnAFzV3O8CeBQ )  => Array ( [type] => http-01 [status] => valid [uri] => https://acme-v01.api.letsencrypt.org/acme/challenge/vkK3qgkWNpDKoRYv0z95on49ZNKbQEfrx5h-vyu1iLg/339693025 [token] => cnq9WS2NAvcnkWV6CxRzejgWSG9tJwf8SwZRzYi0WNI [keyAuthorization] => cnq9WS2NAvcnkWV6CxRzejgWSG9tJwf8SwZRzYi0WNI.J1n-FYM4rGvBpSMWbHOtGpSOWbGtt7c8OdQN_rYPbAM [validationRecord] => Array (  => Array ( [url] => http://stucadoorhilversum.nl/.well-known/acme-challenge/cnq9WS2NAvcnkWV6CxRzejgWSG9tJwf8SwZRzYi0WNI [hostname] => stucadoorhilversum.nl [port] => 80 [addressesResolved] => Array (  => 184.108.40.206 ) [addressUsed] => 220.127.116.11 ) ) ) ) [combinations] => Array (  => Array (  => 2 )  => Array (  => 1 )  => Array (  => 0 ) ) )
What could be the reason Letsencrypt returning the same old date? Has this any thing to do with rate limits?
