    Dear Adhikari, Devendra L,

    If your internet connection is working normally but Microsoft Teams continues to display a "No internet connection" message, the issue may be related to a corrupted Teams cache rather than your network connection.

    Please completely close Microsoft Teams and clear the Teams cache on your device, then restart Teams and sign in again. Cached data can occasionally become corrupted and prevent Teams from connecting properly even when the device has full internet access. For more information and instructions, please refer to this: Clear the Teams client cache

    Moreover, if you are using the Teams desktop app on Windows, here are some troubleshooting steps I recommend you try by following this article: FIX: MS Teams Couldn't Connect to the Internet while the Internet is working.

    If the issue persists, to help narrow down the cause of the issue, could you please provide the following information?

    • Are you using Teams on Windows, Mac, mobile, or a web browser? Have you tried accessing Teams through a web browser? If so, does it work there?
    • Is this a work/school account or a personal Microsoft account (@outlook.com or @hotmail.com)?
    • When did the issue start? Does Teams show "No internet connection" as soon as it opens, or only when you try to sign in or join a meeting? Could you share a screenshot of the error message (remember to remove your personal information before sharing)?
    • Are other Microsoft apps, such as Outlook or OneDrive, working normally on the same device?
    • Are you connected through a VPN, proxy, corporate network, or security software that could be affecting the connection?
    • Have you already tried clearing the Teams cache, signing out and back in, or reinstalling Teams?
    • Are any other users in your organization experiencing the same issue?

    Looking forward to your update. If you have any questions or if I have misunderstood anything, please feel free to reach out.

    If Microsoft Teams says there is no internet even though the connection is working, use these checks:

    1. Try signing in again in Teams.
      • Select the Sign in banner or button.
      • Complete the sign-in prompts, including MFA if prompted.
      • If the sign-in window does not appear, check the notification area near the clock for the Teams icon with a badge, then open it.
      • If it still does not open, quit Teams from the notification area and reopen it.
    2. Make sure the required network is connected before opening Teams.
      • If the organization requires a VPN, connect to the VPN first.
      • Avoid switching between Wi-Fi, hotspot, or other networks while Teams is open.
    3. If Teams works in a browser but not in the desktop app, update browser trust and cookie settings.
      • In Control Panel > Internet Options > Privacy > Advanced, accept First-Party and Third-Party cookies and enable Always allow session cookies.
      • In Internet Options > Security > Trusted Sites > Sites, add:
        • https://login.microsoftonline.com
        • https://*.teams.microsoft.com
      • Administrative rights may be required. These settings can also be deployed by Group Policy.
    4. Check whether Windows is detecting internet access correctly.
      • Run PowerShell: 
             Get-NetConnectionProfile
      • If IPv4Connectivity shows Internet, internet access is available.
      • If it shows NoTraffic or LocalNetwork, Windows is not detecting internet access correctly.
    5. If not behind a proxy, test name resolution.
      • Run: 
             nslookup dns.msftncsi.com
      • If it resolves, internet access is available.
    6. Test the Microsoft connectivity check URLs in a browser.
      • Open:
        • http://www.msftconnecttest.com/connecttest.txt
        • http://ipv6.msftconnecttest.com/connecttest.txt
      • If they return Microsoft Connect Test, internet access is available.
    7. If Windows still does not register internet access, a registry change may help.
      • Warning: editing the registry can affect system networking if done incorrectly.
      • Open Registry Editor.
      • Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator
      • Create a DWORD (32-bit) Value named UseGlobalDNS and set it to 1.
      • Restart the device.
    8. If Teams still shows offline behavior, check firewall or proxy access.
      • Teams connectivity issues are commonly caused by firewall or proxy restrictions.
      • Required Teams URLs, IP addresses, and ports must be allowed.

    If the issue started only in the Teams desktop app and Teams on the web works, the problem is likely with the desktop client sign-in path or local network detection rather than the internet connection itself.
