Teams connection issues

Dear D46-Gregnier,

Good day! Thank you for posting to Microsoft Community. We are happy to help you.

Based on your description, I understand that you have a query "Teams connection issues."

1. Have you checked to ensure your internet connection is stable? You can test this by running a speed test or trying different network.
2. Have you checked to make sure you have the latest version of Microsoft Teams installed? Updates often include fixes for known issues.
3. Have you tried clearing the cache to see if can help resolve the issue? Closing Teams > Navigating to %appdata%\Microsoft\Teams on your computer > Deleting the contents of the Cache folder.
4. Have you checked to ensure that your firewall or proxy settings are not blocking Teams? You may need to whitelist specific URLs and IP addresses used by Teams. Troubleshoot connectivity issues with Teams client - Microsoft Teams | Microsoft Learn.
5. If the desktop app is giving you trouble, try using the web version of Teams at teams.microsoft.com. and check if there is any difference.
6. Close any unnecessary applications that might be using up bandwidth or system resources.

If these steps don’t resolve the issue, it might be helpful to contact your IT support team for further assistance. They can check for any specific network configurations or restrictions that might be affecting Teams.

Let me know if you need more detailed instructions on any of these steps! Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. Thank you for your help.
