Ping of chicks nationwide failed, SSH connection failed, but BTA panel could still access.

admin

1. The small chickens can't ping all the nodes in China, but they can ping all the foreign nodes.
  2. The small chicken installed an X-UI yesterday and opened a node for himself, which he used for one day. Also, another panel was installed on the small chicken's server, other than that, nothing else has been installed.
  3. Is this indicating that the IP has been blocked by the domestic high walls? Should I change my IP?
  4. But I don't understand why only some ports were blocked when the IP was blocked. Otherwise, how could the panel be able to open?
