Hello @J-F_Gauthier 

This is a very generic error and the error is likely due to misconfiguration during the IIS installation. Have you tried reinstalling the IIS (Installing IIS from Windows Server User Interface)Alternatively, could you please try the solution provided below?

Add the following to your web.config:

      <requestLimits maxQueryString="32768"/>

Thank you.
