我的负载均衡器目标组显示为“不可用"- 我如何进一步调试? [英] My load balancer target group shows up as "Not available" - how do I debug this further?

问题描述

我已经创建了一个网络负载平衡器和一个目标组.然后我尝试为负载均衡器创建一个侦听器，但目标组在下拉菜单中显示为不可用".

我的下一步调试是什么?非常感谢您的帮助.

添加侦听器页面也有协议和端口字段，任何协议错误的组都不可用.选择一个可用的目标组然后更改为不同的协议会导致页面显示错误，例如TCP_UDP 侦听器无法将流量转发到 TCP 目标组.您必须选择兼容的目标组或更改侦听器协议."

I've created a Network Load balancer and a target group. Then I try to create a listener for the load balancer, but the target group is showing up as "Not available" in the pulldown menu.

What can be my next step to debug this? Much appreciate the help.

解决方案

The UI appears to have changed, but I had a similar problem (NLB showing an unassigned target group grayed out in the listener's dropdown). When starting over, I had to make sure that the target group protocol was TCP or whichever protocol the balancer would be forwarding to.

The Add Listener page also has Protocol and Port fields, and any groups with the wrong protocol were unavailable. Selecting an available target group and then changing to a different protocol caused the page to show an error like "TCP_UDP listeners cannot forward traffic to TCP target groups. You must select a compatible target group or change the listener protocol."
