Set up a custom domain at United-Domains
How to point your domain registered at United-Domains to your Sosta website. You manage DNS records in the portfolio area of the domain.
What you need
- A United-Domains domain (e.g. deinhaus.de)
- Access to your United-Domains account
- 5 minutes of your time
Step by step
Sign in to United-Domains
Go to united-domains.de and sign in. At the top you find the area "My portfolio".
Dein Bildschirm: United-Domains login and portfolio
Pick the domain
Open "My portfolio" and click the domain you want to use for Sosta.
Dein Bildschirm: United-Domains portfolio with domain list
Open Manage DNS records
In the domain detail view switch to "Settings" or "DNS" and open "Manage DNS records".

Create the CNAME record for www
Click "Add record" and choose type CNAME. Enter the following values and save.
| Typ | CNAME |
| Name / Host | www |
| Wert / Ziel | cname.sosta.app |
| TTL | 3600 |
At United-Domains you can enter the target value with or without a trailing dot (cname.sosta.app or cname.sosta.app.) — both work.
Create the A record for the apex domain
For the bare domain without www (deinhaus.de) you create an A record: "Add record" → type A. Values:
| Typ | A |
| Name / Host | @ (or leave empty for the apex) |
| Wert / Ziel | 72.60.83.165 |
| TTL | 3600 |
With the CNAME for www and the A record for @ your domain is reachable in both spellings. Keep both entries.
Verify in Sosta and go live
In Sosta go to Website → Settings. Enter your domain under "Custom domain" and click "Verify DNS". United-Domains DNS usually propagates within 30 minutes.
Once verified, Sosta automatically obtains the TLS certificate (HTTPS). Typically 1–5 minutes.
When the TLS status switches to "ISSUED", go to Website → Go live and click "Go live".
Notes & common problems
United-Domains updates its interface occasionally, so menu labels can change slightly. What always matters are the record values above: CNAME www → cname.sosta.app and A record @ → 72.60.83.165.
You only change the web records (A and CNAME). MX records and all email settings stay unchanged — your mail keeps working as before.
Most likely the entries have not propagated yet. Wait 30 minutes and try again. If it still fails after 2 hours:
- Check that the CNAME (www) and the A record (@) are really saved
- Make sure the United-Domains nameservers are active (not external ones)
- Test with
dig www.deinhaus.de CNAMEanddig deinhaus.de Ain the terminal
Let's Encrypt provisions the certificate every 5 minutes. If PENDING persists after 30 minutes: write to us at hallo@sosta.app with your domain — we check the TLS provisioning log.
