I get this error when I look at the log file associated with the website. What is the solution? Or a problem that can be solved? What should we do?

Looks like your web application is unable to connect to the SQL server. This may be caused by several reasons. Please check and verify all of these points are satisfied:
1) The connection string at AppData==>dataSettings.json is incorrect
2) The  SQL server is not running
3) The application pool doesn't have appropriate permission as a user in the database.
Feel free to contact me if you need any help/suggestions. I will be more than happy to assist you.
