Immediately after a clean install of OpenCart 3.0.3.7 I was able to log in to the Admin section and the front end. But, after importing products and customers, once logged out, I can no longer log back in to the Admin section. Front end logins still work. If I put in the correct Admin username and password nothing happens. The entered information remains in the fields, no error message of any kind visible. If I change the username or the password to an incorrect format, I get an error message: No match for Username and/or Password.
This has happened with 3 clean installed with no changes to any files.
I found the solution here in the forum at the page below. The problem was caused by changing the time zone.

I just installed ver 3.0.3.7 and going through editing the store details
System -> Settings -> Store -> Local -> Time Zone
I set the time zone to America/Detroit (-5:00) and was unable to login. I found several posts which addressed this issue, but the one which worked was changing the session engine from db to file in the system/config/default.php and system/config/catalog.php files.
Making the edit to the database worked for me:
Log-in to your database
go to oc_settings table
sort key column and locate config_timezone
Change the value to UTC
save and you should be able to log in
