Local Router Error on Updating Plugins

I’m using the latest version of Local on Windows 10. When I try to upload plugins, I always get this error:

Local Router Error. Our apologies for the inconvenience. The Local router is not able to connect to the site you requested.”

I’ve reset, restarted, updated etc. But still the same problem!! I’ve seen other similar problem but on Mac. I’m on Windows.

Please help!!
