推荐答案

Hello

首先，请确保Windows防火墙允许流量，有关此方面的指南，请参见:

Firstly, ensure that the Windows Firewall is allowing the traffic, guides on this are here:

其次，确保您的网络安全组允许流量通过.

Secondly, ensure that your Network Security Group is allowing the traffic through.

第三，如果您使用的是Azure负载平衡器，应用程序网关或防火墙，请确保端口已正确NAT.

Third, if you are using an Azure load balancer, Application Gateway or firewall, then ensure that the port is NAT'd correctly.
