Experiencing a "Network Error" when deploying from Azure OpenAI Studio to Copilot Studio is a known issue that several users have encountered :
Use an InPrivate or Incognito Browser Window: Some users have found that deploying from an InPrivate or Incognito window resolves the network error. This approach can help bypass potential browser caching or extension conflicts.
Log Out of Multiple Microsoft Accounts: Being logged into multiple Microsoft accounts simultaneously can cause conflicts. Ensure you're logged out of all accounts, then log back in with the account associated with your Azure OpenAI and Copilot Studio resources.
Switch to the "Old Look" Version of Azure OpenAI Studio: Some users have reported success by switching to the "Old Look" version of Azure OpenAI Studio when deploying to Copilot Studio. This version might have different configurations that bypass the network error.
Check for Service Updates or Known Issues: Microsoft periodically updates its services, and certain issues may be region-specific or temporary. Review the Azure OpenAI Service and Copilot Studio documentation or forums for any announcements regarding known issues or maintenance activities.
Review Deployment Logs and Settings: Ensure that all configurations, such as API keys, endpoints, and resource groups, are correctly set up. Misconfigurations can lead to deployment failures. Additionally, reviewing deployment logs can provide insights into the specific cause of the error.
