If you're experiencing issues connecting to Bot Libre from the ARC Bot Libre skill, here are a few troubleshooting steps you can take to resolve the issue:

1. Verify Email and Application ID: Ensure that you have verified your email with Bot Libre and obtained an Application ID. This is a crucial step for the API calls to work. If you haven't verified your email or obtained an Application ID, please follow these steps:

   • Visit https://botlibre.com and log in to your account.
   • Go to User Settings and verify your email if you haven't done so.
   • In the User Settings, press the "Obtain" button next to Application ID to get your Application ID.

2. Check Bot Privacy Settings: If your bot is set to private on Bot Libre, ensure that you have marked it as private in the ARC Bot Libre skill configuration. If the bot is not marked as private in ARC but is private on Bot Libre, it may cause authentication issues.

3. Re-enter Credentials: Sometimes, re-entering your Bot Libre username and password in the ARC Bot Libre skill configuration can help. Ensure that you're entering the credentials correctly without any typos.

4. Refresh Bot List: After ensuring all settings are correct, try pressing the "Refresh Bot List" button again in the ARC Bot Libre skill configuration to see if your bot appears.

5. Check ARC and Bot Libre Compatibility: Ensure that both ARC and Bot Libre are up to date. Compatibility issues may arise if either platform has received updates that affect how they interact.

6. Firewall and Internet Connection: Verify that your internet connection is stable and that no firewall or security software is blocking ARC from accessing Bot Libre's services.

7. Contact Support: If you've tried all the above steps and still face issues, consider reaching out to Synthiam's support or the Bot Libre support team for further assistance. There might be specific issues related to your account or technical glitches that they can help resolve.

Remember, the Bot Libre skill in ARC requires a proper connection to Bot Libre's services, and issues can arise from various factors, including account settings, network restrictions, or software updates.

The one thing to note as Athena said is make sure there’s an internet connection.
