Please don't just post the error message into other issues and follow the issue template for bugs. What version are you using? What code did you use?

[denghejun]

Very common code from samples:
supabase_flutter: ^2.6.0

await Supabase.initialize(
      url: AppConfig.supabaseServerUrl,
      anonKey: AppConfig.supabaseServerAnonKey,
      realtimeClientOptions: const RealtimeClientOptions(eventsPerSecond: 10),
    );

supabase = Supabase.instance.client;

channelPlayerMatch = Application.supabase.channel(
      'AGOODMAINLAND_GLOBAL_PLAYERMATCHCHANNEL',
    );

channelPlayerMatch.onBroadcast(event: NetCore.EVENT_PLAYER_LEAVE_MATCH, callback:
        (payload, [_]) {
        print('[${NetCore.EVENT_PLAYER_LEAVE_MATCH}]: received player leave match');
      }
    }).subscribe();

Can you rollback your code, you recently released realtime channel version cause big issue for my app. players can not see all other's position in game.

I found the actual issue is the subscribe((status,error){
print(status);
}) the status sometimes always return: RealtimeSubscribeStatus.timedOut, and after a while, the status became to "RealtimeSubscribeStatus.closed", and then never came back again, it will show the issue like "Bad state: Cannot add event after closing
"

With #1019 being merged now, this issue should hopefully be solved now. You can try it by upgrading supabase_flutter to 2.7.0. If you still experience any issues, please create a new issue.

Got RealtimeSubscribeStatus.timedOut sometime, from China. The situation is sometime I got subscribed , sometimes I got timeout. Is the realtime API blocked from China? any workaround to fix this?
