Solution 1Recommended

Refresh Authentication and Browser Environment

Resolve temporary browser glitches and stale authentication tokens that commonly trigger fetch errors.

Often, the "Client Request Aborted" error is caused by an expired session token or conflicting browser extensions preventing the request from reaching the server.

1
Sign out of Power Automate

Click on your profile picture in the top right corner of the Power Automate dashboard and select 'Sign out'.

2
Clear browser cache

Open your browser settings, navigate to the privacy or history section, and clear your cache and cookies for all time.

3
Test alternative browser modes

Open an Incognito or Private browsing window, navigate back to Power Automate, log in, and attempt to run the flow again.

Refresh Authentication and Browser Environment
Quick Diagnostic: If the flow runs successfully in an Incognito window, a third-party browser extension (such as an ad blocker) is likely causing the network interruption.

Frequently Asked Questions

Why does Power Automate suddenly say 'Failed to fetch'?

This error usually occurs when the browser cannot establish a connection to the Microsoft servers. It is frequently caused by a temporary drop in internet connectivity, strict browser privacy settings, or an ad-blocking extension intercepting the web request.

How do I know if my firewall is blocking Power Automate?

If you only experience the 'Network Error' while connected to your workplace network or a VPN, but the flow works perfectly on a personal network or cellular data, your firewall or proxy is likely blocking essential Microsoft endpoints.

Does clearing browser cache delete my Power Automate flows?

No. Your flows are securely saved in the Microsoft cloud. Clearing your browser cache only removes local temporary files and session data, which forces a fresh login and often resolves 'Client Request Aborted' errors.
