I'm having trouble installing the Ladybug plug-in

Hello, I downloaded ladybug plugin. This problem occurs when installing it later. I didn’t understand why. And I couldn’t solve this problem.

at first remove the lbt once and after that sure your connection working correctly and i recommend you to use a vpn

I would try the Pollination Grasshopper plugin installer. It installs the latest version of the Ladybug Tools with all the simulation engines.
