Are you running an older version of dotnet-try?

Try this:

> dotnet tool uninstall -g dotnet-try
> dotnet tool install -g Microsoft.dotnet-try

Hi @jonsequitur. I followed the steps and made sure that I was running the latest version.

After reinstalling, whenever I try to run dotnet try or dotnet try demo the server runs fine but I can't get past certificate errors.

Firefox provides the following error: An error occurred during a connection to localhost:51557. PR_END_OF_FILE_ERROR

I've already tried using removing and adding again the localhost cert using dotnet dev-certs with no success.

I have other dotnet core projects running on localhost and the certificate is accepted by all browsers.

hey @lucavgobbi afaik those issues with firefox and errors like yours may be caused by your security software or even by the security settings of your ISP
