Can't connect Binance API using websocket

[K-tang-mkv]

When I command "wscat -c wss://stream.binance.com:9443/ws/btcusdt@trade"
it got an error "error: connect ETIMEDOUT 69.171.246.9:9443" everytime.

I tried the exact command and it works:

Maybe a problem in your router, your vpn or your country from where you connect?

I did the same thing on my Mac, but I really don't know what's going on. It always gets an error whether I use VPN. And I'm from China mainland.

I just had my VPN connect with China and when I run the command I get this:

C:\Users\macro>wscat -c wss://stream.binance.com:9443/ws/btcusdt@trade
error: read ECONNRESET

So, logical conclusion to me is that China ipaddress gets blocked by binance

when i use tcping to test the endpoint, I got a message that the endpoint was closed.
MacBook-Air ~ % tcping 69.171.246.9 9443
69.171.246.9 port 9443 closed.

Thank you! I already know the reason!
