.at domain and SSL certificate: set up HTTPS correctly
Your .at domain is registered, but the browser displays a certificate warning? Separate registration, DNS and HTTPS so you can find the right place to complete the setup.
Read guide ↗The essentials
First check confirmed registration and the complete domain name in your account. Then review outstanding verification notices, connections to your chosen website or mail service and the next domain deadline. Payment, registration and a finished website are separate checks.
1. Check registration, not only payment
Start with the complete domain name in your order confirmation and customer account. Compare the spelling, including the extension. A successful payment or a basket entry alone does not establish completed registration. If processing is still underway, follow the existing order and its instructions. Do not place the same paid order again simply because its status is unclear. Note the order reference and ask through your account. Completed registration and a working website are also different results: the name can be registered successfully while you connect your website service later.
Check the domain and existing order in your account2. Keep records and responsibilities together
Keep the confirmation, payment record and intended domain holder details with your project documents. Agree who manages the customer account and which reachable email address is used for it. An invoice addressed to someone does not prove that person is also the recorded domain holder. If details are unclear, have them checked rather than simply rewriting account information. For a project involving an agency or association, establish who can request changes and who only edits the website. Do not put passwords or verification links into a shared task list. Your records should explain decisions without distributing another access credential.
Distinguish holder, billing and technical access3. Read verification notices in the account and inbox
Check confirmation messages and the notices beside your domain. Verifying your account email and any separately requested verification of domain contact details are different steps. If the account shows an outstanding domain verification and a deadline, complete that specific instruction in time. Do not assume a universal deadline applies to every .at domain. An unavailable status also does not mean everything is complete. Check the latest messages, including spam, and ask for help with a missing or expired link. Open your account through the known website; never reply to an unexpected verification message with a password or card details.
4. Decide which service provides the website
Your domain is the address; the website needs a suitable service. Domains sold at atdomain.at do not include hosting or website creation. Ask your chosen website service for its specific connection instructions. Then decide whether to maintain DNS records on the existing default nameservers or use your own nameservers. Changing nameservers is not required for every website connection and does not automatically copy existing records. Check whether the address should work both with and without www. Record the required values and change only the necessary entries. If the website comes later, you can manage the domain separately in the meantime.
Check active nameservers before a changeUnderstand DNS and HTTPS separately5. Treat email as its own connection
A working website does not prove email is configured under the same domain. If you need custom addresses, choose a mail service whose plan supports custom domains. We do not sell mailboxes at atdomain.at. Create the required recipients at the mail service and follow its current DNS instructions. Then test both an incoming message and a reply using the intended sender. If you are not setting up email yet, still use an already reachable contact address for your domain account. An address that only exists in your plans is not a reliable destination for important domain notices.
Plan mailboxes and alias addresses6. Read the included term and next deadline correctly
Check “Prepaid through” or “Renew by” in your account. The 3-year plan includes registration and two annual renewals for €39.00 total; the technical expiry is updated annually. A shorter technical date alone is therefore not a reason to order the same included renewal again. Have the plan status checked if anything is unclear. For a new standard .at domain, the one-year price is €12.99 total; further annual renewal currently costs €15.99 total. Outside the included term, arrange renewal in time at the price offered then. There is no automatic card charge. Non-payment is not a confirmed cancellation.

7. Test completed connections before publishing the address
Open the intended website address on your phone and another device. Check the correct content, complete address and valid HTTPS. If applicable, test both www variants and the email connection separately. A recently changed DNS answer can remain different across existing caches. If something fails, note the time and exact error rather than starting new orders or making unrelated changes. Publish the address once the functions your project actually needs have been checked. If you are only securing the name for now, explicitly record that the website and email have not yet been connected.
