Hi @bigd46

Well as you mention that you are facing 500 internal server error - so first we exactly needs to identify whats the error is there !

do one thing - from your magento 2 root directory/app/bootstrap.php file

open bootstrap.php file - and uncomment the below line by removing # : 

ini_set('display_errors', 1);

then it will display the error on the browser , post that error so its help us to troubleshoot the issue !

Hope it helps

Fatal error: Uncaught Exception: Warning: ini_set(): Cannot find save handler 'redis' in /home/magento/vendor/magento/framework/Session/SessionManager.php on line 563 in /home/magento/vendor/magento/framework/App/ErrorHandler.php:61 Stack trace: #0 [internal function]: Magento\Framework\App\ErrorHandler->handler(2, 'ini_set(): Cann...', '/home/magento/v...', 563, Array) #1 /home/magento/vendor/magento/framework/Session/SessionManager.php(563): ini_set('session.save_ha...', 'redis') #2

Here is what I found something about redis. It works in the site.

Hi @bigd46

Seems like you have Redis Cache issue on your server , so its mainly not related to Magento but its related to Redis Cache using Server as well !

This is known issue and also reported on Github as well . below i am sharing the links for the same !

No I figured it out, you need the php-redis and configure seesion-save-handler
