Magento 2 Admin Page Error: Your current session has been expired

Some time fresh Magento or after upgrade to the latest version you may see this error on admin area  Magento 2 Admin Page Error: Your current session has been expired

let’s see the possible solution!

first, check for a current session lifetime

php bin/magento config:show admin/security/session_lifetime
If there is no entry issue the following query

insert into core_config_data (config_id, scope, scope_id, path, value) values (null, ‘default’, 0, ‘admin/security/session_lifetime’, 36000);
If entry is there increase the session life time. It can be done in two ways

UPDATE core_config_data SET value = 86400 WHERE path = ‘admin/security/session_lifetime’;
OR

Issue the following command from Magento root directory

php bin/magento config:set admin/security/session_lifetime 86400
php bin/magento cache:clean
hopefully This should solve your problem.

Kindly let me know in comment if it worked for you or not!
