How to Fix “No Internet Connection Was Found” in Microsoft Teams

If Microsoft Teams displays the error “No internet connection was found. Please reconnect and try again”, it can prevent you from joining meetings, sending messages, or accessing shared files. What makes this issue confusing is that your internet may appear to be working normally in browsers and other apps.

This error typically occurs due to network configuration issues, DNS problems, firewall restrictions, corrupted Teams cache, proxy/VPN interference, or outdated app components. In most cases, the problem is local to your system rather than an actual internet outage.

If you are seeing this error in Microsoft Teams on Windows 11, follow the detailed troubleshooting steps below.

This refreshes your network configuration and resolves DNS-related issues.
