Thank you @György-Farkas it works.

Hi,
I have one of the first omega 1 (one) RC1 from kickstarter long time ago,
working on project after some time, and i want to upgarde firmware but
nothing is happened when im doing it trough web settings, or from SSH console.
I have properly setup Wifi, and i tested it trough console, its working ok.
But im getting stuck at

Checking latest version online...
ERROR: request timeout, internet connection not successful

once again i am 100% sure that wifi is working and i have working internet on device.

Is this old device still have a support for firmware upgrade or do i need to do some tinkering around it.

Thank you.
