Slow to open cosnole after enabling SSL

[li jerry <di...@hotmail.com>]

Hi All

The ACS version I use is 4.15.0.0
I set ACS Enable ssl according to the document https://www.shapeblue.com/securing-cloudstack-4-11-with-https-tls/.

After ACS enabled SSL, it was found that the process of opening the VM console was very slow.

Chrome debug mode discovery
Open https://****.**********.com/client/console?cmd=access, it takes 97ms
Open https://****.**********.com/resource/noVNC/vnc.html, it takes 15-20s

My cpvm, the configuration is 4C/4G

This is very fast before enabling ssl, and the entire console can be opened in about 3-5 seconds.
May I ask where I set it wrong?


Thanks everyone for your help!

Do you see a TLS handshake taking time?
Can you analyze with the network tools (in Browser) what is taking time?
That is unusual, and not seen normally - it should take 1-5sec to establish
a noVNC console to a VM.

Best,
