@Vyacheslav-Bachynskyi We made some upgrades to the firmware server so there was some downtime last week. Should be running smoothly now. Let me know if it isn't! @Thorsten-Ludewig The Omega is most likely having issues connecting to your WiFi network. Can you please make an issue at https://github.com/OnionIoT/wdb40/issues and I'll provide support.
