如何克服领事中的问题 500（后端响应错误）？

Question

嗨，我的 macbook，我使用的是 consul 版本 1.8.0

并使用此配置启动 (consul agent -config-file desky.json):

{
 "node_name": "desky.local",
 "ui": true,
 "retry_join": ["172.20.20.31"],
 "advertise_addr": "172.20.20.1",
 "data_dir": "/tmp/consul"
}

我知道这里报告了这个问题，但似乎人们仍然有问题并且没有回复它已修复。 https://github.com/hashicorp/consul/issues/7288

在我运行 consul agent 的 macbook 命令行中，我在启动时收到以下日志，其中有一些错误。

好吧，Hashicorp 应该在抛出错误时将其作为一个可能的例子来解决，

我在 consul 服务器端使用了这个：

-bind 0.0.0.0
-client 0.0.0.0

解决了这个问题。
