What is Error Dolphin-028 on Ubisoft?
If you’re launching Ubisoft Connect and you see this message:
“There was an error during your login to Ubisoft Connect. Please restart your client and try again. (Error Dolphin-028)”
…then you’re facing Dolphin-028, a network-related error that stops your Ubisoft app from connecting to its servers.
This usually has nothing to do with your Ubisoft account itself. It’s more about how your device is connecting (or failing to connect) to Ubisoft’s online services.
Why Are You Seeing Dolphin-028?
Here are the most likely reasons:
- 🔌 Network connectivity issues – Wi-Fi drops or ISP blocks
- 🔐 Firewall or antivirus interference – Security tools mistaking Ubisoft Connect for a threat
- 🌍 VPN or proxy conflicts – Encrypted connections confusing Ubisoft’s servers
- ⚙️ Corrupted Ubisoft Connect app or cache
- ❌ High MTU settings or DNS problems
- 🧱 ISP restrictions or regional blocks
Let’s fix that together.
How to Fix Error Code Dolphin-028 (Step-by-Step)
1. Restart Everything
- Restart your computer
- Restart your modem/router
- Relaunch Ubisoft Connect
This clears temporary connection glitches.
2. Run Ubisoft Connect as Administrator
Right-click on the Ubisoft Connect shortcut > Click Run as administrator.
Gives the app proper permissions to access the internet.
3. Disable VPN or Proxy (Temporarily)
VPNs and proxies can interfere with region-based connections.
On Windows:
- Settings > Network & Internet > Proxy
- Make sure “Use a proxy server” is off
On Mac:
- System Settings > Network > Advanced > Proxies tab
- Uncheck all proxy options
4. Clear DNS and Set Public DNS
In Command Prompt (Windows):
bashCopyEditipconfig /flushdns
Then switch to public DNS:
- Preferred: 8.8.8.8
- Alternate: 1.1.1.1
This boosts connection reliability.
5. Whitelist Ubisoft in Antivirus/Firewall
Antivirus or firewall tools can block Ubisoft Connect.
- Add Ubisoft Connect as an exception in Windows Firewall or your antivirus settings.
- Make sure uplay.exe is allowed through public and private networks.
6. Reinstall Ubisoft Connect
If nothing works:
- Uninstall Ubisoft Connect
- Restart your device
- Download the latest version from ubisoft.com
- Install and log in again

- Retry launching Ubisoft Connect
💬 FAQs – Error Dolphin-028 Ubisoft
Q1: What does “Dolphin-028” actually mean?
It’s Ubisoft’s internal code for a network connection failure, usually caused by local issues like your internet, firewall, or settings—not your Ubisoft account.
Q2: Will my account be banned or affected?
No, this error has nothing to do with account suspensions or bans. Your games and data are safe.
Q3: Can I still play games offline while this error happens?
Some single-player Ubisoft games support offline play. But online features, syncing, and multiplayer will not work until the error is fixed.
Q4: Is this error happening only on PC?
Most commonly, yes. It mainly affects Ubisoft Connect for Windows, though console users can occasionally see similar login issues.
Q5: Can router settings cause this?
Absolutely. A high MTU setting or strict NAT type can block connections to Ubisoft servers. Try setting MTU to 1430 or enabling UPnP in your router settings.
Q6: Will resetting my Ubisoft password help?
It won’t fix Dolphin-028 since it’s not an account issue. But if you suspect login issues in general, a password reset won’t hurt.
Q7: How long should I wait before contacting Ubisoft support?
If you’ve tried all the above steps and waited at least 15–30 minutes without success, reach out at https://www.ubisoft.com/help
Final Thoughts: Don’t Let Dolphin-028 Block Your Game Time
While frustrating, Dolphin-028 is usually fixable in minutes. It’s often your device trying—and failing—to communicate with Ubisoft’s login servers.
Whether it’s your VPN, DNS, firewall, or a temporary server issue, the steps above should help you get back into your game without stress.
