Troubleshooting Connection Issues

Common Issues and Solutions

Cannot connect to remote device

1. Check if CoDesk is running on the remote device
2. Verify the ID — make sure you entered the correct remote ID
3. Check server settings — ensure both devices point to the same ID server
4. Firewall — allow CoDesk through the firewall on both devices
5. Network — ensure both devices have internet access

Connection is slow / laggy

1. Network quality: Use a wired connection if possible
2. Display settings: In the toolbar, try lowering the image quality
3. Close heavy apps: Reduce load on the remote machine
4. Relay mode: If P2P fails, traffic goes through the relay server. Check if direct connection is possible

Black screen after connecting

1. Permission issue (macOS): Grant Screen Recording permission to CoDesk
2. GPU acceleration: Try disabling hardware acceleration in CoDesk settings
3. Multiple monitors: Switch to a different monitor using the toolbar
4. Restart CoDesk on the remote device

Password rejected

1. Ensure you're using the correct one-time or permanent password
2. The one-time password changes periodically — get the latest from the remote device
3. If using a permanent password, verify it hasn't been changed
