Troubleshooting

Sync Not Working

Problem: Sync doesn't happen automatically

Solutions:

1. Check Kobo is connected to Wi-Fi
2. Verify AutoSyncEnabled=true in config
3. Check SyncFrequency is not set to 0
4. Test with manual sync first
5. Check Bookmann logs for connection attempts

Connection Refused

Problem: "Connection refused" or "Server not reachable"

Solutions:

1. Verify Bookmann is running on your computer
2. Check the server URL and IP address are correct
3. Ensure Kobo is on same Wi-Fi network as computer
4. Temporarily disable firewall to test
5. Try accessing Bookmann URL in your browser first

Authentication Failed

Problem: "Authentication failed" or "Invalid credentials"

Solutions:

1. Verify username and password in config file
2. Check your account is active and not locked
3. Try logging in to Bookmann web interface
4. Ensure password doesn't contain special characters that need escaping
5. Reset password if needed

Configuration File Not Saving

Problem: Changes to Kobo eReader.conf are lost

Solutions:

1. Make sure Kobo is ejected safely after editing
2. Check file permissions (should be writable)
3. Try a different text editor (Notepad++, VS Code, Sublime Text)
4. Backup the file before editing
5. On Mac, ensure you're not editing the package directly

Sync Only Works Manually

Problem: Manual sync works, but auto-sync doesn't

Solutions:

1. Verify AutoSyncEnabled=true in config
2. Check SyncFrequency is not 0
3. Kobo only syncs when connected to Wi-Fi
4. Some Kobo models require Wi-Fi to be manually connected
5. Check Bookmann device management page for connection errors

Books Not Appearing in Kobo

Problem: Books added to Bookmann don't show on Kobo

Solutions:

1. Kobo needs books to be sideloaded (manually transferred via USB)
2. Bookmann syncs PROGRESS, not book files
3. Transfer book files to Kobo's Documents folder via USB
4. Kobo will then sync progress for those books with Bookmann
5. Check that book formats are supported by Kobo

Conflicts Not Showing

Problem: Conflicts between devices aren't being detected

Solutions:

1. Check Bookmann Conflicts page
2. Ensure both devices have synced recently
3. Conflicts only detected when progress differs within 5 minutes
4. Manually sync both devices to trigger conflict detection
5. Review conflict resolution settings

Security Best Practices

1. Use HTTPS: If deploying Bookmann publicly, configure SSL/TLS
2. Strong Password: Use a secure password for your Bookmann account
3. Network Security: Ensure your Wi-Fi network is secure (WPA2/WPA3)
4. Regular Updates: Keep Kobo firmware updated
5. Device Authorization: Only approve devices you recognize

Network Configuration

Local Network (Recommended)

For home use, keep Kobo and Bookmann on the same local network:

Kobo Wi-Fi: 192.168.1.x
Bookmann: 192.168.1.x

Remote Access

For access outside your home network:

1. Set up port forwarding on your router (port 8765)
2. Configure SSL/TLS on Bookmann
3. Use a dynamic DNS service for constant hostname
4. Update Kobo config with public URL:

   [Sync]
   ServerURL=https://yourdomain.com/api/sync/kobo
   

Performance Optimization

Battery Life

To extend Kobo battery life:

1. Use longer sync intervals (15-30 minutes)
2. Sync only on Wi-Fi (not cellular if your Kobo has it)
3. Disable unnecessary Kobo features
4. Keep Kobo in sleep mode when not reading

Sync Speed

To improve sync speed:

1. Ensure strong Wi-Fi signal
2. Use local network (not remote access)
3. Keep Bookmann and Kobo on same network
4. Close other apps using Wi-Fi bandwidth
5. Reduce number of books syncing at once
