Troubleshooting Network and Connectivity Issues

Client Devices Cannot Connect

Symptom: Dermi Atlas Professional works on the host computer but not on secondary devices like an iPad or Laptop.

Solutions:

1. Firewall: This is the most common cause. See Firewall Configuration to ensure ports are open.
2. Network: Ensure both devices are on the exact same Wi-Fi/LAN. Do not use Guest networks, as they often isolate clients from one another.
3. URL: Check Dermi Atlas Manager for the correct URL (verify the port number, e.g., :15015).
4. Ping Test: Try to ping the host IP address from the client device to verify basic network connectivity.

Intermittent Connection / URL Changes

Symptom: The connection URL works one day but stops working the next.

Cause: Dynamic IP assignment (DHCP) by the router causing the host IP address to change.

Solution: Set a Static IP for the host computer running Dermi Atlas Professional. See Configuring a Static IP for instructions.

WebSocket Connection Errors

Symptom: "Reconnecting..." messages appear frequently, or data is not syncing live between the host and client.

Solutions:

1. Firewall: Ensure WebSocket ports (default 15815 and 15845) are allowed through the firewall.
