📌 Please note: The following steps and screenshots are based on the status at the time this article was written. The user interface or names of the tool may have changed in the meantime.
If you notice any discrepancies, we recommend checking the current instructions in the tool, looking in the provider's help center, or contacting the provider's support team.
These instructions cover two situations, and both are configured the same way inside Cloudflare:
Cloudflare sits between your domain provider and Onepage — you bought your domain somewhere else (e.g., IONOS, Strato, GoDaddy) and route it through Cloudflare.
Cloudflare is your domain provider — you registered the domain directly with Cloudflare Registrar.
In both cases, the DNS records and the proxy/SSL/TLS settings described below are identical.
Preparations in Cloudflare
Step 1: Register or log in
Register with Cloudflare or use your existing login details to log in.
Step 2: Connect your own domain to Cloudflare
Open your account's home page and enter your existing domain.
Or, if you wish to register a new domain, you can purchase it directly here.
Step 3: Copy the name servers
Cloudflare will then show you two name servers that you will need for further setup. Please be sure to save these.
Connect domain to Cloudflare
Step 1: Log in to your domain hosting provider
Log in to the hosting provider where you purchased your domain (e.g., Hosteurope, Strato, IONOS).
Step 2: Open domain settings (DNS)
Go to the DNS or nameserver settings for your domain in the customer area.
Step 3: Enter Cloudflare nameservers
Enter the two nameservers that were previously displayed in Cloudflare. Then save the changes.
📌 Please note: The change may take up to 24 hours to be fully implemented worldwide (DNS propagation).
Step 4: Check the connection in Cloudflare
Then log back into Cloudflare and check whether the domain is displayed as "active". Once the connection is successful, you can manage your domain entirely through Cloudflare.
Connect domain in Cloudflare to Onepage
Step 1: Open DNS settings
In Cloudflare go to Domain → Overview → Press the 3-dot button → Configure DNS.
Step 2: Connect domain via A record or CNAME
If you want to connect your main domain (for example yourdomain.com), please create the following DNS entries:
A record:
Type: Select "
A" as the record type.Name: Enter "
@" to assign the root domain.IPv4 address: Enter the IP address of Onepage:
216.162.200.200TTL:
Auto
CNAME:
Type: Select "
CNAME" as the record type.Name:
wwwTarget: Copy and paste your domain here (for example yourdomain.com)
TTL:
Auto
If you want to connect a subdomain to Onepage (for example offer.yourdomain.com), please create the following DNS entry:
CNAME:
Type: Select "
CNAME" as the record type.Name: e.g.,
offerTarget:
whitelabel.onepage.ioTTL:
Auto
Then click Save.
📌 Please note: If you are experiencing connection problems, you can try switching the proxy to "DNS only" as a test.
Cloudflare proxy (orange cloud) and SSL/TLS
When you create the DNS records above, Cloudflare shows a cloud icon next to each record. An orange cloud means Cloudflare’s proxy is switched on for that record; a grey cloud means the record is DNS-only. Both options work with Onepage, but each needs a different SSL/TLS setting. Pick the option that fits your needs below.
Option A: Keep the proxy on (orange cloud)
Choose this if you want to keep Cloudflare’s proxy features. Leave the cloud orange and set the SSL/TLS mode as follows:
In Cloudflare, open SSL/TLS → Overview → Configure:
Set the encryption mode to Flexible.
Leave "Always Use HTTPS" (SSL/TLS → Overview → Edge Certificates) on its current setting — you do not need to change it.
Option B: Turn the proxy off (grey cloud / DNS-only)
Choose this if you do not need Cloudflare’s proxy features. Click the cloud icon on your Onepage-related records so it turns grey (DNS-only). With DNS-only you can leave Cloudflare’s SSL/TLS mode as it is — Onepage manages the certificate.
Which SSL/TLS mode should I use?
Cloudflare SSL/TLS mode | Supported? |
Flexible | ✅ Recommended, permanent |
Full | ⚠️ Not reliable |
Full (strict) | ❌ Not supported |
Off (grey cloud) | ✅ Full Onepage-managed SSL |
Connect domain in Onepage
Step 1: Log in to Onepage
Log in to Onepage: Onepage Login
Step 2: Open settings
In the page overview of the project where you want to connect your domain, click on "Settings".
Step 3: Connect your own domain
Go to the "Domain settings" tab and click on "Connect your own domain".
Step 4: Enter domain
Enter the desired domain in the domain settings (e.g., yourdomain.com for the main domain or offer.yourdomain.com for a subdomain).
📌 Please note: Enter the domain only in the format "yourdomain.com", without www. in front.
Then click on "Next step" and select the connection method "A-records" for the main domain.
In the next step, you can check whether there are any incorrect entries that should be deleted. The entries previously set by Onepage should already be stored correctly.
When connecting your subdomain, the system will automatically pick the CNAME method instead.
🎉 Done! You have now successfully connected your domain to Onepage via Cloudflare. 🎉
📌 Please note: Connecting the domain may take several hours (up to 48 hours in rare cases). It is therefore acceptable if the domain does not work immediately.
Frequently Asked Questions (FAQ)
Cloudflare tells me that I can only create an A, AAAA, or CNAME record. Is that correct?
Cloudflare tells me that I can only create an A, AAAA, or CNAME record. Is that correct?
Yes, if your domain is already connected to another provider, your previous entries will be transferred to Cloudflare. These ensure that the content of your previous website continues to load when the domain is accessed.
In order for the domain to be correctly connected to the new destination (Onepage), the outdated entries must be deleted.
Why can't I access my page even though I have configured all settings correctly?
Why can't I access my page even though I have configured all settings correctly?
In many cases, this is not a configuration problem, but rather a local cache or DNS effect.
Please try accessing your website using a different device (e.g., laptop, PC, or smartphone) or alternatively via a different network and check whether it is accessible there.
This is often only due to a DNS changeover that has not yet been fully completed or to cached data in the browser.
