See: Where to find log files

Possible HTTP Error 500 black screen messages:

HTTP Error 500 (Dynamic)

"The file {filename} has not been pre-compiled and cannot be requested"

HTTP Error 500 (Static)

"This error is triggered by ASP.NET and likely indicated a configuration problem rather than a runtime error in SquaredUp itself"

HTTP Error 500 (Dynamic)

OpenAccess/Index : System.Web.HttpException

"The file '/SquaredUp/Views/OpenAccess/Index.cshtml' has not been pre-compiled, and cannot be requested"

Procedure

The issue can be resolved using the following steps.

You may need to connect to your SquaredUp server (How to connect to your SquaredUp server).

1. In IIS stop the SquaredUp DS application pool.
2. On the SquaredUp Server open the following folder:
   C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\SquaredUp[version number]
3. Delete the folder within it which is named with a randomly generated GUID.
4. ​​Start the SquaredUp DS application pool. If you check you should see a new randomly named folder has been created as the SquaredUp DS assemblies are re-copied into the new folder.
5. Browse to SquaredUp DS. The web page should open successfully and you should be able to log in.

Symptoms

You are using multi-factor authentication (MFA) and users see this error when trying to log in to SquaredUp DS:

HTTP Error 500 (Static)

"This error is triggered by ASP.NET and likely indicated a configuration problem rather than a runtime error in SquaredUp itself"

Procedure

This error can be caused by using multi-factor authentication (MFA) for the Microsoft Azure Management application.

The solution is to create a similar Conditional Access policy requiring multi-factor authentication for the SquaredUpAzure enterprise application (or, if preferred, to add the SquaredUpAzure enterprise application to the existing Microsoft Azure Management MFA Conditional Access policy).

For more information see Microsoft Create a Conditional Access Policy

Users logging in to SquaredUp DS for the first time may see the message Need admin approval if an administrator did not tick Consent on behalf of your organization at the permissions requested stage of SquaredUp DS deployment (see Troubleshooting users being unable to logon). An administrator needs to give consent in the Azure portal as described below:

1. In the Azure portal search for Enterprise Applications.
2. Within Enterprise applications search for SquaredUpAzure and select the SquaredUpAzure enterprise application mentioned in the Need admin approval message.

   

3. Click on Permissions from the menu (under Security).
4. Click the button Grant admin consent for <tenant>.
