#2

I fixed [Operation1] issue.

I was set the variable HTTP_PROXY and HTTPS_PROXY to activate the UiPath Studio license from my company network that requires proxy server to connect to the internet.

I remove HTTP_PROXY and HTTPS_PROXY variable so that I fixed the issue.

#3

I solved [Operation2] issue.
I was set http_proxy key in C:\Windows\SysWOW64\config\systemprofile\AppData\Roaming\NuGet\Nuget.config.
Despite the impossible connection to the UiPath Academy’s Orchestrator, the above setting remained.

I remove the above settings.
