None command is possible to execute on DX CLI, from my company network.
ERROR running force:org:open: connect ETIMEDOUT 188.8.131.52:443.
I know that DX CLI is based on Heroku and it uses Node.js
Looking for the same error on Heroku, people who faced the same issue has resolved when enabling Port 5000 (which is why I think it is blocked here in my network)
I also know that Node.js has its own proxy.
Has someone already faced this issue?
