Hi! I understand that you have two computers on your Currys Cloud Backup account, and one is saving perfectly while the other is showing as "offline." Let's get to the bottom of this together.

To start, could you tell me if the computer showing "offline" is currently connected to the internet? And have you noticed if the Currys Cloud Backup app there has been updated recently or if any changes were made to network settings or firewall?

In the meantime, here’s a step-by-step to troubleshoot the offline status on your Windows 10 computer:

1. Check Internet Connection: Make sure the computer is connected to the internet and the connection is stable.

2. Restart the App and Computer: Close the Currys Cloud Backup app, reboot the computer, then reopen the app. Sometimes a fresh start helps reconnect.

3. Verify Sign-in Status: Make sure you're still signed into the app with the correct Currys account. Sometimes a sign-out or token expiry may cause offline status.

4. Firewall and Security Software: Ensure that your Windows Firewall or any antivirus isn't blocking the Currys Cloud Backup app. You can add it to the allowed programs or firewall exceptions.

5. Update the App: Check if there’s an update available for Currys Cloud Backup and install it.

6. Check Backup Settings: Open the app on the offline computer and verify if the backup folders and drives are correctly selected and recognized.

7. Run Network Troubleshooter: On Windows, go to Settings > Network & Internet > Status > Network troubleshooter to detect any network issues.

If after these steps the computer still shows offline, please let me know what you find or if you encounter any issues during these steps. We can look into more advanced fixes then.

Does this sound okay to start with?
