Can't run 2.10 after install. Couldn't connect DB

Hello. I just have had an unsuccessful try to run Contao 2.10 after clean install.
The error is

Code:

Fatal error: Uncaught exception Exception with message Could not connect to database (Access denied for user ' dreel_site1'@'localhost' (using password: YES)) thrown in /home/d/dreel/sites/site1/public_html/cms/system/libraries/Database.php on line 78 #0 /home/d/dreel/sites/site1public_html/cms/system/libraries/Database.php(136): Database->__construct() #1 [internal function]: Database::getInstance() #2 /home/d/dreel/sites/site1public_html/cms/system/libraries/System.php(147): call_user_func(Array) #3 /home/d/dreel/sites/site1public_html/cms/system/modules/backend/Backend.php(49): System->import('Database') #4 /home/d/dreel/sites/site1public_html/cms/contao/install.php(63): Backend->__construct() #5 /home/d/dreel/sites/site1public_html/cms/contao/install.php(910): InstallTool->__construct() #6 {main}

I have checked 2.9.5 on the same hosting and it works normally.
