Are you stuck here? Signing by correct username and password, but it returns error because Current Session Has Been Expired. It maybe because there is no path that has admin/security/session_lifetime
value on core_config_data
table of your database.
You can add it into that table by adding 1 row of that has the value :
config_id : NULL (automatically)
scope : default
scope_id : 0
path : admin/security/session_lifetime
value : 86400 (1 day by 60*60*24, it's in second)
Next, you need to clean cache : php bin/magento cache:clean
or bin/magento cache:flush
. Then hard refresh the browser, and sign in.
