I deployed my app, done in ASP.NET Core MVC, on the server, in IIS.
However, an error appears when I pass the first screens of my app… It seems to be a problem in the querying of the database. Here is the error:
"""

Is this in fact a problem in the querying of the database?

Cannot resolve the collation conflict between "Latin1_General_CI_AI" and "SQL_Latin1_General_CP1_CI_AI" in the like operation.
Check your query for the LIKE keyword. You can try to change the collation at your query level to make both columns compatible in collation.
Format your SQL query with instant sql formatter:
