The error 'magento 2 redis session issue' can arise due to several factors related to Redis and its integration with the Magento 2 platform. Inaccurate configuration or incorrect setup of Redis as a session storage engine in Magento 2 is one possible cause of this error. Such misconfiguration may cause session data not to be correctly saved or retrieved from Redis, leading to the error.
Another potential cause of this error is compatibility issues between various versions of Redis and Magento 2. If the version of Redis used with Magento 2 is incompatible, it might affect the session management system, resulting in the mentioned errors.
To fix the 'magento 2 redis session issue', try different solutions. Firstly, check the Redis configuration settings in Magento 2 to ensure proper setup as the session storage engine. Confirm that the correct credentials have been provided, and Redis is running efficiently.
If the configuration settings are correct, then try upgrading or downgrading Redis to a compatible version with your current Magento 2 version. Alternatively, update Magento 2 to the latest version, which may include bug fixes and compatibility improvements for Redis. Before making any changes, do not forget to back up your website to avoid data loss.
Lastly, if none of the above measures work, consider using an alternative session storage engine other than Redis, such as file-based session storage or database-based session storage. Keep in mind that these alternatives may have their own limitations and drawbacks and should be selected carefully based on specific needs.
