Troubleshooting Server Connection Errors

If your KA Labs or Shasta software won’t connect to the internal database (NexusDB Server), you’ll likely see a startup error or the control panel light will stay red. This article walks you through the most common ways to resolve those connection problems.

🧯 Common Symptoms

• KA_Labs or Shasta Software won’t launch or gets stuck on startup

• "Unable to connect to server" message

• Red light in the KA_Labs software control panel

• You recently installed the software on a new PC

  
  
  

🛠️ Step-by-Step Troubleshooting

🔍 Step 1: Check the NexusDB Server Service

1. On your keyboard, press Windows + R, type services.msc, and press Enter

   

2. In the Services window, scroll to find NexusDB Server V3

   

3. Check the Status column:

   • If blank, right-click and select Start

     

   • If already running, continue to the next step

     

4. Try launching KA_Labs or Shasta again

🧹 Step 2: Reset the NexusDB Folder (If Step 1 Fails)

If the NexusDB server still doesn’t work:

1. Go back to the Services window

2. Right-click NexusDB Server V3 > click Stop

3. Open File Explorer

4. Go to: C:\ProgramData\

🧼 Note: This is a hidden folder. Enable “Hidden Items” in the View tab to access it.

1. Locate and delete the folder called: NexusDB3

2. Go back to the Services window
3. Right-click NexusDB Server V3 > click Start
4. Relaunch KA_Labs software

✅ If successful, you should now see a green light in the control panel.

🧩 Still Not Working?

• Double-check your database settings in KA_Labs:

  • IP Address: 127.0.0.1

  • Hostname: (leave blank)

  • Location: LAN / WAN

• Confirm your firewall or antivirus isn’t blocking KA_Labs or NexusDB

• Restart your computer and try again
