C# Asp.net身份登录无法登录

我刚刚在我的网站上测试了登录功能。最近登录一直工作良好，但现在我不断收到错误

Login failed for user 'Dolapo'.
This session has been assigned a tracing ID of 'e25c9fb4-3ec4-4ce1-9f7f-c01988c856a7'.        Provide this tracing ID to customer support when you need assistance.`

在线

var user = await UserManager.FindAsync(model.UserName, model.Password);`

然而，我尝试用用户Ben而不是Dolapo登录

任何帮助都将不胜感激

我检查了与数据库的连接字符串，但密码不正确

请验证连接字符串中的用户名和密码，以确保其与数据库的凭据匹配。

是否尝试清除缓存以确保输入数据以启动新会话？这应该是现成的。你是怎么修改的？
