Unable to connect to ilo4 with the remote console

[gantonio73]

Hello everyone, I wanted to ask for advice on the following problem, I have a ProLiant DL380 Gen9 server before making the SPP "P05006_001_spp-2018.03.0-SPP2018030.2018_0226.84", I could connect to the server with the remote console of ilo4 without any problem, now after the update, I connect to the remote console of ilo4 but in the java window after the word "connected", at the bottom left, after a few seconds I see the words "no video", and I can not interact with the system , what happened to you? And yet I opened all the right doors on the firewall, ie 17990, 17988, 443

Waiting for your kind advice, thank you.

Antonio.
