Hello StarlingX Team, I finally solved the horizon error, the port number was different. I don't know why the port was changed, but anyway the port number was 8080, not 80. But I'm now facing new obstacles, Duplex PXE Booting. I succeed to connect PXE mode, but no more process.. In Controller-0, I can find below result, [image: image.png] And another node that should've been controller-1, shows below letters on the display. 1) All-in-one Loading rel-19.01/installer-bzImage......... Loading rel-19.01/installer-initrd............................................................................ready. I waited this task for a day, but no changes. Any help would be very appreciated. Best Regards, Jaewook. ================================================ *Jaewook Oh* (오재욱) IISTRC - Internet Infra System Technology Research Center 369 Sangdo-ro, Dongjak-gu, 06978, Seoul, Republic of Korea
