I see you're getting an error when saving a Copilot Studio topic with a Power Automate flow attached. The error message says "Unable to save the topic. Check your connection and try again."
Since your internet connection is working fine, here are the steps to troubleshoot this:
Check Power Automate flow status
Open the Power Automate flow separately
Verify the flow is turned on
Look for any errors or warnings in the flow itself
Test the flow independently to confirm it runs without issues
Verify connection references
In your Copilot Studio topic, check all connection references used by the Power Automate action
Each connection must be active and authenticated
Re-authenticate any connections showing warnings
Remove and re-add the Power Automate action if connections look stale
Simplify and test
Create a minimal test topic with only the Power Automate action
Try saving this simpler version
If this saves successfully, the issue is elsewhere in your topic
If this fails too, the problem is with the Power Automate integration itself
Clear browser cache
Log out of Copilot Studio
Clear your browser cache and cookies
Log back in and try again
Try a different browser or incognito mode
Check for known issues
Review the Microsoft 365 admin center for any service disruptions
Check the Power Platform admin center for environment health
Look at recent updates that might affect Copilot Studio
Environment permissions
Verify you have proper permissions in both Copilot Studio and Power Automate
Confirm your environment allows cross-service integrations
Check if your admin has any DLP policies blocking connections
If none of these work, try recreating the Power Automate flow from scratch and connecting it fresh to a new topic. Sometimes the connection metadata gets corrupted and starting over resolves the issue.
