无法使用 ssh 连接到 gcloud？
can not connect to gcloud using ssh?
使用促销积分（300 美元开户促销），我曾经使用 SSH 连接我的 VM gcloud compute ssh instance_name 一切都很好。
促销信用结束，我将项目链接到我的结算帐户。那么现在，运行同样的SSH连接return这个错误
ERROR: (gcloud.compute.start-iap-tunnel) Error while connecting [4033: 'not authorized'].
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
我不明白...VPC 没问题，防火墙打开了所有端口。
我真的必须设置 iap 隧道吗？为什么正常的 SSH 连接不再有效？
如果有人可以确认（在我更改运行良好的内容之前），谢谢。
