When you have the v2.33 (latest and greatest) iLO2 firmware installed, you might surprised that the HTTPS requests are taking forever. This is due to the new Diffie-Hellman key exchange.
When you are not worried by security threats as you have your firewall fence high up or using a VPN to reach your systems remotely you the best thing you can do is downgrade to ILO2 firmware v2.32.
When the downgrade has done the ILO 2 Log will happily tell you that you have *upgraded* your system, again!
