【问题描述】：
我有三个 cockroachdb 节点，其中两个使用 DigitalOcean（一个在旧金山和纽约）和第三个 TX 服务器。我遵循了Manual Deployment 文档并启动了我们的本地节点，然后我们的远程节点返回：
*
* WARNING: The server appears to be unable to contact the other nodes in the cluster. Please try
*
* - starting the other nodes, if you haven't already
* - double-checking that the '--join' and '--host' flags are set up correctly
* - not using the '--background' flag.
*
* If problems persist, please see https://www.cockroachlabs.com/docs/v1.0/cluster-setup-troubleshooting.html.
*
我 nmaped 从我们的纽约服务器到我们的 TX 节点并且端口是打开的。然后我用--logtostderr 运行cockroach start 并注意到它正在尝试解析到本地IP，即使我告诉它--join REMOTEIP:PORT。

我是否错误地设置了本地节点主机名？ troubleshooting documentation 不是很有帮助。我什至尝试将 TX 主机更改为本地 IP，但这并没有解决问题。
编辑：
我们的防火墙导致了通信问题。解决后，我们的 TX 节点需要 --advertise-host 参数。
