（gcloud.beta.compute.ssh）[/usr/bin/ssh]已退出，返回代码为[255]

尝试使用ssh连接google云计算机引擎（macOs Catalina）

并得到错误

ssh: connect to host 34.105.11.187 port 22: Operation timed out
ERROR: (gcloud.beta.compute.ssh) [/usr/bin/ssh] exited with return code [255].

ssh: connect to host 34.105.11.187 port 22: Operation timed out

我试着

ssh -I ~/.ssh/mac-vm-key asd61404@34.105.11.187

也得到了错误

ssh: connect to host 34.105.11.187 port 22: Operation timed out
ERROR: (gcloud.beta.compute.ssh) [/usr/bin/ssh] exited with return code [255].

ssh: connect to host 34.105.11.187 port 22: Operation timed out

所以我找到了这个代码来诊断它

gcloud compute ssh —zone "us-west1-b" "mac-vm" —project "mac-vm-282201" —ssh-flag="-vvv"

返回

OpenSSH_7.9p1, LibreSSL 2.7.3
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 48: Applying options for *
debug2: resolve_canonicalize: hostname 34.105.11.187 is address
debug2: ssh_connect_direct
debug1: Connecting to 34.105.11.187 [34.105.11.187] port 22.

我不知道，我怎样才能解决这个问题

提前谢谢
