無法透過 Cloud Identity-Aware Proxy 連線

無法透過 Cloud Identity-Aware Proxy 連線
錯誤代碼:4003
原因:failed to connect to backend

連線至 VM 遭拒。
請確定以下事項:
VM 設有防火牆規則,允許來自 IP 範圍 35.235.240.0/20、通訊埠 22 的 TCP 輸入流量
– 目標 VM 上的 SSH Daemon 正在運作中

您可以嘗試不使用 Cloud Identity-Aware Proxy 來連線。

# 要使用瀏覽器的Cloud shell 連線,要另外開一個IP,  34.80.130.73

================================================================================
Don’t use GUI mode for load testing !, only for Test creation and Test debugging.
For load testing, use CLI Mode (was NON GUI):
jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]
& increase Java Heap to meet your test requirements:
Modify current env variable HEAP=”-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m” in the jmeter batch file
