    Umbraco 10 - Clean installation - Could not connect to database (debug attempts have been made)

    Hey there.

    I have been using Umbraco for some time, since version 7 and there's a new project that I am starting from scratch with v10.0.1.

    I can't get the installer to connect to the database, though.

    I have checked the following:

    • I can connect to the database, using the same data, through Management Studio
    • I changed the Startup.cs code to create a connection of my own via SQLClient, with the same data, which was successul
    • Looking at the SQL Server Profiler, there's no connection attempt coming from the website (Umbraco) when trying to configure the database settings
    • I have other websites, with other versions of Umbraco installed. This is the first v10 one I am trying to setup
    • .net core 6.0.3 is installed
    • SQL Server Express version is 15

    I'm kinda lost here. Any tips?

    Thank you very much in advance.

    I reckon no one else had this problem?

    A bit more of data:

    When submitting the form, I get the following from postvalidatedatabaseconnection:

    {"Type":"https://tools.ietf.org/html/rfc7231#section-6.5.13","Title":"Unsupported Media Type","Status":415,"Detail":null,"Instance":null,"Extensions":{"traceId":"00-acaed7850191623adc6e92a412dcf271-c8e9c92aeeb9cbd8-00"}}

    I managed to get to a conclusion and I will leave it here since it may help someone in the future.

    I had a URLRewrite rule in the web.config file to force all URLs to be lowercase.

    That was forcing a redirection from PostValidateDatabaseConnection to postvalidatedatabaseconnection, which triggered a 415 error and didn't allow it to go through.

    Once I removed that rule, it worked like a charm.
