# Fix “Can’t Reach This Page” Error for Custom Domains (CAA DNS Record Update)

# Fix “Can’t Reach This Page” Error for Custom Domains (CAA DNS Record Update)

**If you see an error such as:**

“Hmm… can't reach this page. It looks like the webpage at [your custom domain] might be having issues, or it may have moved permanently to a new web address.”

This may be caused by a **CAA DNS record** on your parent domain that restricts who is allowed to issue SSL certificates. Simplebooklet must be able to issue a certificate through **Let’s Encrypt** to support the secure** https://** version of your custom domain.


### Why This Happens

Some domain providers or parent domain configurations include **CAA (Certification Authority Authorization) records** that limit SSL issuance to specific providers. If Let’s Encrypt is not included, Simplebooklet cannot generate or renew your SSL certificate — causing your custom domain to appear offline or unreachable.


### ✅ How to Fix It: Add a CAA Record

Please add the following DNS record to your domain’s DNS zone:

| Type | Name | Flags | Tag | Value |
| ---- |
| CAA | @ | 0 | issue | letsencrypt.org |


### Where to Add This

You can add this record in your domain provider’s DNS management area (such as GoDaddy, Namecheap, Cloudflare, etc.). This record explicitly authorizes **Let’s Encrypt** to issue SSL certificates for your domain and its subdomains.


### After Updating the Record

* Save your DNS settings.

* DNS changes may take up to **24 hours** to propagate.

* Once complete, Simplebooklet will be able to issue or renew your SSL certificate, and your custom domain will load correctly over **https://**.


### Why SSL Is Required

Simplebooklet automatically uses secure HTTPS connections to protect your content and your audience. Without SSL authorization, your domain will not load properly.


### Need Help?

If you're unsure how to add this DNS record, your domain provider’s support team can do it for you. Just provide them with the table above.

You can also contact Simplebooklet support with a screenshot of your DNS settings if you’d like us to confirm everything is set up correctly.
