There was an error saving the HTTPS developer certificate to the current user personal certificate store

Question

I have installed the .Net Core SDK and I am trying to install the developer certificates so that i can work on the HTTPS projects which come by default

I have run:

    dotnet dev-certs https

but i encounter the error:

    There was an error saving the HTTPS developer certificate to the current user personal certificate store.

I restarted the computer, ensured no browser was running and tried again but it still doesnt work.

Any help would be greatly appreciated

EDIT:

I am using Windows 8.1, and my .net Core version is 2.1.5

Answer 1

Try this command:

dotnet dev-certs https --clean

and then

dotnet dev-certs https
dotnet dev-certs https --trust

If that doesn't work try deleting your localhost certificate manually and then run those commands again.

I had the very same problem but on Mac. There I had to uninstall .net core SDK and delete all the folders in the library too. Which actually might be a solution as well. And then I ran those commands again and they worked.

Anyway if it is not mandatory for you to use https in your development stage you can comment

app.UseHttpsRedirection();

inside your Configure method in your startup.cs and remove https addresses inside Properties/launchSettings.json
