Microserver Gen8 iLo4, Console freezes

Hello.

I have Microserver Gen8 with latest iLo 4 firmware 2.62, latest BIOS and all latest firmwares on other components.

I have a problem with iLo4 remote console. When I need it, I lauch it from .net or java - no difference, console freezes.

Here is the video, what I about (take a look on flash cursor, when I enter letters):

I started to make a video screen recording, and when I click "Start", there is no freezes:

As soon as I turn off the recording - the console freezes again.

This problem occurs from any PC, notebook. There is no difference between OS on endpoints.

But, on smartphones, with iLo4 app - there is no such freezes. All works fine.

Therefore, I updated all the firmware and installed the latest iLo4 2.62 firmware - no results.

What is it, i dont understand?

Thank you.
