iLO 4 Remote Support Registration Error (HTTP Server Protocol Error)

[jhoffman]

I'm having trouble getting my ML30 Gen9 to connecto to remote support directly.  I SSH'd into iLO and verified I could ping google's DNS (8.8.8.8) and also could ping hpe.com (had to look up the ip through the ping command in cmd.exe, but was able to ping the IP address for HPE that was listed).  I have no outbound filters on the firewall.  I've tried downgrading fw to 2.3 and 2.4, currently on iLO version 2.5.  Any ideas?  Screenshot of error attached.

Hi,

Can you analyse the network trace on the Proxy/firewall to confirm if any packets are being blocked during the registartion process. I have encountered similiar issues and isolated to some Firewall's blocking ciphers during the registartion process. Also will be good to log  a case with HPE IRS Support for more help on this.
