How Can You Easily Fix the Frustrating Ubisoft Connect Dolphin-028 Login Loop?

What Are the Most Effective Solutions for the Annoying Ubisoft Connect Dolphin-028 Error?

The Ubisoft Connect Dolphin-028 error traps users in a persistent login loop, displaying a “Restart” prompt and blocking access to all Ubisoft games—even single-player titles. This error usually signals a problem connecting to Ubisoft’s servers, either due to server-side issues or local network misconfigurations.

Key Causes of Dolphin-028

• Ubisoft server outages or maintenance (often confirmed on Ubisoft Support pages)
• Local network problems, such as:
• DNS misconfiguration
• High MTU values
• VPN or proxy interference
• Traffic-filtering tools (e.g., GoodbyeDPI) disrupting secure connections

Solution 1: Restart Your Router and Check Ubisoft Server Status

• Power cycle your router several times.
• Visit Ubisoft’s server status page and official forums to verify if there’s a known outage. If Ubisoft’s servers are down, local fixes won’t work until service is restored.

Solution 2: Run Ubisoft Connect as Administrator

Right-click the Ubisoft Connect shortcut and select “Run as administrator.”

For a permanent fix: Right-click > Properties > Compatibility > Check “Run this program as an administrator.”

This ensures the launcher has the necessary permissions for network access and system changes.

Solution 3: Reset Your Ubisoft Password and Enable Two-Factor Authentication

1. Go to Ubisoft’s website, log in, and access Account Management.
2. Change your password and enable 2-Step Verification for added security.
3. Sign out of Ubisoft Connect on other devices before signing in again on your PC.

Solution 4: Sync Your System Clock and Use a Reliable Time Server

Right-click the taskbar clock > Adjust date and time > Sync now.

If issues persist, switch to the NIST server:

Control Panel > Clock and Region > Date and Time > Internet Time > Change settings > Enter time.nist.gov > Update now.

Solution 5: Connect via Mobile Hotspot to Bypass Network Restrictions

Use your phone’s mobile data (USB tethering or hotspot) to connect your PC.

If this works, your main Wi-Fi or ISP may be blocking Ubisoft Connect.

Try restarting your router or disabling VPNs/proxies before reconnecting to your main network.

Solution 6: Switch to a Public DNS Server (Google or Cloudflare)

Go to Network settings > Change adapter options > Right-click your connection > Properties > IPv4 > Properties.

Enter:

• Preferred DNS: 8.8.8.8
• Alternate DNS: 8.8.4.4

In Command Prompt, run ipconfig /flushdns or reconnect to Wi-Fi.

Solution 7: Set Network MTU to 1430 for Stable Packet Transmission

1. Open PowerShell as Administrator.
2. Check current MTU: netsh interface ipv4 show subinterfaces
3. Set MTU: netsh interface ipv4 set subinterface “YOUR_INTERFACE_NAME” mtu=1430 store=persistent
4. Restart your PC or network adapter.
5. To revert, reset the MTU to its original value (commonly 1500).

Solution 8: Renew Your Local IP Address and Clear Ubisoft Launcher Cache

Delete cache: C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache

In Command Prompt (Admin):

• Release IP: ipconfig /release
• Renew IP: ipconfig /renew

This refreshes your network configuration and resolves potential IP-related blocks.

Summary of Best Practices

• Always check for Ubisoft server outages first.
• Run the launcher with admin rights.
• Keep your system clock accurate.
• Use reliable DNS and appropriate MTU settings.
• Refresh your local network configuration if needed.

By following these steps, you can effectively resolve the Dolphin-028 error and restore access to your Ubisoft games.
