How to add PowerVault ME5xxx to SCG/VE

Hi,

I'm having problems connecting my ME5 to the SCG/VE
The official documentation says the following:
“ PowerVault ME5 array appear after  SupportAssist has been configured in PowerVault Manager to use the Secure Gateway"

So,
I have activated the SupportAssist on my ME5
I have the newest SCG /VE -> 5.22.x
I use the right port -> 9443
and I use the right Access Key and PIN

The result from my connection check "check support-assist-connection mode gateway" is: 
Connection State: Connected
Status: success
Message: ok

But, my ME5 doesn't appear in the SCG device list.

Does anyone know this problem?
