To resolve the issue of your ProWeatherLive Personal Weather Station (PWS) not connecting to the server or failing to update, follow these detailed steps:

1. Check Network Connection
- Verify that your Wi-Fi network is operational. Ensure other devices can connect to the internet without issues.
- If your PWS has a local display, check if it shows a proper connection status to the Wi-Fi.

2. Power Cycle Devices
- Unplug the power from your PWS console/ObserverIP and your router.
- Wait for about 30 seconds, then reconnect the power back to the router first. Allow it to fully reboot.
- After the router is back online, power on the PWS. This simple reset can clear network connection issues - learn more.

3. Check ProWeatherLive Settings
- Connect to your ObserverIP using a computer or smartphone. Ensure that the ObserverIP's settings are correct, as issues with the configuration can prevent it from communicating with the server.
- Look at the server settings to confirm that you are using the correct server information for ProWeatherLive. If you need to reset these settings, follow the manufacturer's guide on setting up your station - learn more.

4. Check for Firmware Updates
- Open the ObserverIP interface and check if there are any available firmware updates for your PWS model. Outdated firmware can lead to connectivity issues - learn more.

5. Router and Firewall Configuration
- Ensure that your router is not blocking the connection to the ProWeatherLive server. You may need to check your firewall settings to see if any configurations are preventing this connection.
- Consider temporarily disabling any firewall or security settings to test connection stability - learn more.

6. AP Mode Connection
- If your PWS allows, try putting it into Access Point (AP) mode to connect directly to your device for configuration. This can sometimes help diagnose connectivity issues - learn more.

7. Examining Data and Report Errors
- If your PWS intermittently shows an online status yet data isn't updated, this could indicate a problem in data reporting. Check if you see errors in the data logs of your PWS and address them depending on the error type. Often, reconfiguring your data upload settings may fix this issue - learn more.

8. Contact Support
- If you have gone through these steps and still experience issues, consider contacting ProWeatherLive support for further assistance. They may provide specific troubleshooting for server connection problems.

By following these steps, you should be able to troubleshoot and hopefully resolve the issues with your PWS connection.
