Extension manager is not working in typo3 latest version

 
Your TYPO3 project are working fine except the typo3 extension manager , when you take the extension manager from the admin panel and you got the message is “The connection was reset” as we get the message like when there is no internet connection.

The reason could be that xampp has a too small default stack size, leading to a stack overflow and connection reset.

Could you try to add “ThreadStackSize 8388608” to your httpd.conf

ThreadStackSize 8388608

it will work fine after adding this line into your httpd.conf
