Hi Logan,

Thank you for your response.

1) I can access this url in a web browser, but it seems that SnapDelevop cannot, as I have one error about this:

2) Yes, nuget.org is checked in the package resources list:

3) The same error when restoring tha packages:

So here's the issue, my SnapDelevop cannot connect to nuget.org but I don't know why. I've read about this error and I've not found the solution:

- I'm not using a proxy and there's nothing wrong in the nuget.config file

- I'm on a Windows 7, so I don't have a Windows 10 registry key to modify

- Nuget cache deleted, didn't worked.

- I have some applications done in Visual Studio 2015, I have no issues there with nuget

Regards,

Alex.

Hi Alex,

1) Can you access https://api.nuget.org/v3/index.json from this computer? All NuGet packages (including SnapObjects libraries) can be downloaded from nuget.org by default. 

2) Please check your package sources to see whether nuget.org is checked, refer to:

https://docs.appeon.com/snapdevelop2019r3/SnapDevelop_Users_Guide/index.html#package-sources

3) Right-click on your solution, select Restore NuGet Packages, then check the message in Output.

Regards,

Logan
