On trying to get to it in Firefox I was presented with 

SSL_ERROR_BAD_MAC_ALERT 

On trying to get to it through Chrome I was presented with

This site can’t provide a secure connection

10.0.0.2 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

The client and server don't support a common SSL protocol version or cipher suite. This is likely to be caused when the server needs RC4, which is no longer considered secure.

We tried through CLI : 

load -source http://webserverip/iso/ilo2_229.bin /map1/firmware1

However this was giving us errors for some reason

We found a workaround in Internet Explorer is to disable TLS 1.2 (Tools >
Options > Advanced > UNTICK Use TLS1.2). 

After Restarting IE , it logged us into the ilo , however this was not the stop of the problems , upgrading to the latest firmware 1.57 gave us errors

We had to update to 1.28 first , then we could upgrade to the latest , below is a link to someone has all the links to the correct BIN files
