Error during auto-login on phpmyadmin

Hello, We have no moment of Mysql errors when accessing phpmyadmin via CPANEL, this error is as follows: Warning in ./libraries/plugins/auth/AuthenticationCpanel.php#629 mysqli_connect(): (28000/1045): Access denied for user USER @ localhost (using password: YES) Backtrace ./libraries/plugins/auth/AuthenticationCpanel.php#629: mysqli_connect( string ********, string ********, string ********, string ********, string ********, ) ./libraries/plugins/auth/AuthenticationCpanel.php#389: PMA libraries plugins auth AuthenticationCpanel::cp_mysql_auth_check( string ******** , string ******** , ) ./libraries/common.inc.php#694: PMA libraries plugins auth AuthenticationCpanel- authCheck() ./index.php#20: require_once(./libraries/common.inc.php) If we reload our page, this error is no longer present. Do you know where it can come from and how to solve it? Best regards
