iMac cannot connect to a network in Recovery Mode, receive error code -5101F?

Every time i reboot the system and press Control option R (SYS Recovery) i get this message. My IMAC is connected via wifi to the internet and no specific firewall is active. I get the error code -5101F.

Also i see that the version of OS is : UNARCHIVED.

Also no OS updates received anymore. System is i7quad , end 2015

End of Life would be harsh as the systems works fine and i am very pleased with it.

Does anybody knows what i need to do?

Connect your Mac via ethernet to the modem. The WiFi connection may not be on the same protocol as your computer. If your Mac does not have ethernet, USB-C and Thunderbolt-2 to ethernet adapters exist for those Macs.
