Umamusume error code 390 indicates a connection failure between the game and its servers. It often happens due to unstable internet, VPN usage, region restrictions, or ongoing server maintenance. Players can fix it by checking their connection, disabling VPNs, clearing cache, or waiting until server issues are resolved.
