The domain name registry gives you the rights to use the domain. If your domain is not registered to you, Let\u2019s Encrypt will not be able to generate a certificate for it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ0HSXDMT1BCZX6WVRQZ2T\">Is it happening to me?<\/h3>\n\n\n\n<p>If you don\u2019t remember registering your domain name, it is likely that you haven\u2019t gone through the registration process yet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ0Z1MZ6ZYBCM7T4Z08HC4\">How to fix<\/h3>\n\n\n\n<p>If you think this is the case, head to Pair Domains or your domain registrar of choice and register your chosen domain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"the-domains-dns-doesnt-point-to-pair-networks-hosting-servers\">The domain\u2019s DNS doesn\u2019t point to Pair Networks\u2019 hosting servers<\/h2>\n\n\n\n<p>When you add a domain to the Pair Network\u2019s Account Control Center (ACC), you are given name servers. These name servers must be added to your domain name on your domain registrar\u2019s site. If they are not added, then the domain is not actually being hosted by the hosting account.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ20ED3VW63CS3QKWRQSAV\">Is it happening to me?<\/h3>\n\n\n\n<p>Go to your domain registrar and find your domain\u2019s name servers. If you registered a domain with Pair Domains, see our article,\u00a0<a href=\"https:\/\/www.pairdomains.com\/kb\/posts\/301\" target=\"_blank\" rel=\"noreferrer noopener\">Changing Name Servers<\/a>.

Once these have been saved and the registrar has applied the change to the domain, retry Let\u2019s Encrypt.<\/p>\n\n\n\n<p class=\"wp-block-ht-blocks-messages wp-block-hb-message wp-block-hb-message--withicon is-style-alert\">Changes to name servers sometimes take 24 to 48 hours to process. You may have to wait for the name servers to be updated before retrying Let\u2019s Encrypt.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"dns-hasnt-propagated-preventing-lets-encrypt-from-reaching-servers\">DNS hasn\u2019t propagated, preventing Let\u2019s Encrypt from reaching servers<\/h2>\n\n\n\n<p>Making changes to your DNS configuration could cause delays in DNS propagation, thus causing Let\u2019s Encrypt to fail. If you only recently set up or moved the domain that Let\u2019s Encrypt failed on, you may have tried to add Let\u2019s Encrypt before the domain\u2019s name servers (DNS) were fully propagated. When DNS are changed, it sometimes takes from 24 to 48 hours for them to update. DNS configuration changes may have occurred without your realization. Changes to certain domain hosting options in the ACC will cause automatic changes to be made to the DNS configuration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ4Q0BJ439J8GRN8E4THRM\">Is it happening to me?<\/h3>\n\n\n\n<p>If you tried to add Let\u2019s Encrypt to a domain within 48 hours of changing the DNS on your registrar or making domain hosting changes in the ACC, this may be causing Let\u2019s Encrypt failure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ53Y80RMRQV6XVG027R76\">How to fix<\/h3>\n\n\n\n<p>A sure way to fix this problem is to just retry Let\u2019s Encrypt after 48 hours are up. While you can retry Let\u2019s Encrypt before 48 hours, Let\u2019s Encrypt may fail again if the DNS are still not propagated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"your-www-domain-and-non-www-domain-are-separated\">Your www domain and non-www domain are separated<\/h2>\n\n\n\n<p>It is possible to separate the www version of your domain name from the non-www version of your domain name. For example, you may have www.example.com send visitors to a different website than visitors who go to example.com. This can be done by specifically creating a subdomain for the www version of your domain or using DNS. Doing this can complicate the Let\u2019s Encrypt process and ultimately result in a failure to generate a certificate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ6F3KDCNNQAAFR3V35C88\">Is it happening to me?<\/h3>\n\n\n\n<p>If you have separated the www version of a domain from the non-www version, either by DNS or by creating a subdomain, this is the most likely reason for why Let\u2019s Encrypt is not working with your domain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ75VWB498NX79G5QB7DYB\">How to fix<\/h3>\n\n\n\n<p>To fix this, you need to contact our support team so that they can manually setup your domain with Let\u2019s Encrypt. You can find our support team\u2019s contact information on&nbsp;<a href=\"https:\/\/www.pair.com\/support\/\" target=\"_blank\" rel=\"noreferrer noopener\">our support page<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"htaccess-is-blocking-lets-encrypt\">.htaccess is blocking Let\u2019s Encrypt<\/h2>\n\n\n\n<p class=\"wp-block-ht-blocks-messages wp-block-hb-message wp-block-hb-message--withicon is-style-alert\">.htaccess is not available on WP Hosting packages, so this is not applicable to WP Enthusiast or WP Professional.<\/p>\n\n\n\n<p>This is a problem that is more likely to affect customers who have made changes to their .htaccess files. If you have anything in your .htaccess files that affects the .well-known directory, this may cause problems when Let\u2019s Encrypt tries to issues you a certificate. For more information on the .well-known directory, see the<a href=\"https:\/\/tools.ietf.org\/html\/rfc5785\" target=\"_blank\" rel=\"noreferrer noopener\">&nbsp;IETF\u2019s article about the .well-known URI path and how it should be used<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQ9HA8TN6CE4RW3ETBVAHB\">Is it happening to me?<\/h3>\n\n\n\n<p>You can check your .htaccess file and see if any of the contents affects the .well-known directory. Things to look for in particular would be:<\/p>\n\n\n\n<ul>\n<li>Redirect that applies to the .well-known directory<\/li>\n\n\n\n<li>Password or IP based restrictions on the .well-know directory<\/li>\n\n\n\n<li>Rewrites that requests .well-known\/* to return a different file, return an error, or run a script<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQA6NH7GJR8VGBAN79FKB4\">How to fix<\/h3>\n\n\n\n<p>How to fix this problem will depend on what is affecting the .well-known directory. A Redirect could be replaced with a RedirectMatch that can turn off in the .well-known directory or a Rewrite, which can also be turned off in the .well-known directory. For the IP or password restrictions, turn off any restrictions that apply to the .well-known directory. Rewrites that request .well-known\/* to return something different must be removed.

You can find our support contact information on&nbsp;<a href=\"https:\/\/www.pair.com\/support\/\" target=\"_blank\" rel=\"noreferrer noopener\">our support page<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"you-have-custom-firewalls-set-up-on-your-dedicated-or-vps-account\">You have custom firewalls set up on your Dedicated or VPS account.<\/h2>\n\n\n\n<p>If you have a firewall configured that prevents access to the local web server, it may prevent Let's Encrypt from contacting the server. Let's Encrypt uses a web-based Domain Control Validation (DCV), which means that it needs to make contact with the web server in order to validate it. If it is blocked by a firewall, Let's Encrypt will not be able to validate your server and will fail on your domain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQCTX8XSREKGM43C044G0W\">Is it happening to me?<\/h3>\n\n\n\n<p>If you know that you have a firewall set up on your server, this could very well be the problem.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h_01HDKQDAX7W4JKA0THNDKKVVWT\">How to Fix<\/h3>\n\n\n\n<p>It is not possible to issue firewall exceptions for Let's Encrypt to access your server since Let's Encrypt does not publish a list of all IP addresses. This is because providing the IP addresses could cause security issues and the IP addresses are subject to change without notice.<\/p>\n\n\n\n<p>However, there are two possible solutions to remedy firewall blocking: configure your firewall to allow more traffic or get a different kind of certificate.<\/p>\n\n\n\n<p>If you configure your firewall to allow more traffic to the web server, it will allow Let's Encrypt to work on your server. However, if that is not an option for you, you will not be able to use Let's Encrypt on your domain.<\/p>\n\n\n\n<p>In Let's Encrypt's place, you can order a PairSSL certificate. PairSSL uses a DNS-based Domain Control Validation (DCV) instead of web-based DCV, so the certificate will not be deterred by a firewall that blocks all server traffic.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Let\u2019s Encrypt provisioning process is automatic, but can sometimes fail if the domain\u2019s configuration is not set up correctly.&nbsp; Your domain isn\u2019t registered at a domain name registry yet In order to use a domain, it must first be registered at a domain name registry.
