Hi! Sorry to hear you’re running into that "Unable to connect to server" and "Unable to fetch libraries" error in your Prologue app. To get started, could you tell me if this issue started happening suddenly or after any changes like an update or network change? Also, are you able to connect to the internet and other services normally on your Windows device?

Meanwhile, here’s a straightforward step-by-step approach we can try to resolve this:

1. Check Your Internet Connection
Make sure your device is connected to the internet and can browse websites. Try opening a few different sites in your browser to confirm.

2. Temporarily Disable Firewall or Antivirus
Sometimes, security software might block app connections. You can briefly disable your firewall or antivirus to see if that lets the Prologue app connect. If that fixes it, you’ll want to add Prologue to your security software’s allowed list.

3. Restart the Device and App
Close the Prologue app completely, restart your Windows device, and then open the app again. This often clears temporary connection issues.

4. Check for App Updates
Make sure Prologue is updated to the latest version. Updates often include fixes for server connectivity problems.

5. Review Proxy or VPN Settings
If you’re using a VPN or proxy, try disabling it temporarily as that can affect server access.

6. Clear App Cache and Data (if possible)
Within the app settings or Windows settings under Apps, clear any cache or data associated with Prologue.

If none of these steps fix the issue, sometimes the problem can be on the server side. According to a community discussion, some users reported sudden loss of library and server access, which may indicate a temporary outage or server maintenance1.

Let me know what you’ve tried so far or any other details you notice, and we can dig deeper! Are you satisfied with this guidance so far?
