Unable to start Kestrel

Radzen Studio Blazor Server
1

I attempted to run an application I've been working on, but this morning got this error message when compiling:

System.InvalidOperationException: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

Note that I'm using the Azure AD security provider, which has been working well. Is there anything I need to change with the latest version of Radzen? Or are there any configuration changes needed?

Thanks,

Bill

Hi @bdiplacido,

There are no changes in latest Radzen related to project build process. Still if you want you can get the previous version from our changelog:

Hi @enchev,

Thanks for the quick reply. Perhaps there was an update to my system. For anyone else having similar issues I ended up fixing this issue by running the following in a command prompt:

dotnet dev-certs https

This usually happens if you install a new version of .NET Core or somehow delete the existing certificates . Or login as a different user.

We had some Windows updates the other day, and I believe .NET was one of them. It's possible that it deleted the existing certificate.
