[ipxe-devel] Official ipxe.efi fails to chain the 1st time into boot.salstar.sk

[Dreamcat4]

Hi,

We tried this in shell:

iPXE> chain http://boot.salstar.sk/ipxe/ipxe.efi
http://boot.salstar.sk/ipxe/ipxe.efi.... connection timed out (blah error
url)

iPXE> chain http://boot.salstar.sk/ipxe/ipxe.efi
http://boot.salstar.sk/ipxe/ipxe.efi.... ok

2nd time worked.

Nothing is seen on the remote webserver the 1st failed attempt. And other
regular local PC client (eg wget on linux) can download the same file no
problems.

Other urls worked fine the 1st time. For example

iPXE> chain http://boot.ipxe.org/ipxe.efi

I attached to this email a .pcap file of the local packet trace log file.

Its a problem because the 1st connection timeout error (or any other error)
and my ipxe boot menu will exit / abort. It never (from menu script) gets
the change to try again for a 2nd time.


Other times it will fail up to 4 times, then work ok. But in the pcap log
file attached here, it worked the 2nd time.
