HP Network BIOS Update failing

Has anyone run into issues when performing a Network BIOS Update on HP systems? According to the the documentation, the system goes to an FTP site on hp.com and downloads the file. However, when checking the firewall and web logs, only an HTTP log is shown as accepted but nothing blocked. The network update works without issue on an external line or via another firewall (excluding Zscaler tunnel).

Any help would be appreciated.

Hi Raj,

Could you disable RFC 1323 i.e. TCP Timestamp option on the client workstation and give a try?

If the issue is unresolved, please submit a ticket and work with ZTAC.

Kind Regards,

Hi Giriraj,

There is no option in the BIOS for TCP Timestamp. We already have a case open with TAC for a few months now and no progress yet…

Hi Raj,

Please share the ticket number.

Thanks,

Here you go - 850101

Today, I’ve tried to specify a proxy server but still the same results.

Hi Raj,

I’ve provide additional info to the TAM and he will update you via the ticket notes.

Thanks,
Giriraj
