With most recent grub2-2.02-0.80.el7 I only get "unrecognised network address" error. Looks like there is a message "Press any key to continue..." and after a short delay the system boots up. I made a photo of this. Not sure if this is relevant, but *randomly* grub2 also fails to load the file with "invalid magic number". This happens on LAN and this is HTTP Boot so unlikely a TFTP packet drop. Attaching too. Created attachment 1665899 [details]

I was able to reproduce this issue and the problem was that GRUB was not enclosing the literal IPv6 address in square brackets when writing the Host field of the HTTP request header. Reproduced on RHEL-7.8-20200225.1 x86_64 Server *** Bug 1667575 has been marked as a duplicate of this bug. *** Reproduced using RHEL-7.8 Verified using RHEL-7.9-20200623.0 with grub2-2.02-0.82.el7, both IPv6 and hostname cases work fine now. Moving to VERIFIED. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
