Cert Refresh for Local Atlantis Projects
Clear out old certs from %appdata%/ASP.NET/https and clean out the contents - these are all the old certs that have been cached
Run the following commands in the Package Manager Console
PM > dotnet dev-certs https --clean
PM > dotnet dev-certs https --trust
PM > dotnet dev-certs https --check
Close down all Visual Studio instances and then start them back up
Next time you run a react project from Visual Studio - it should grab the fresh cert and you'll be good to go.
