Hi,

Can you please have a look and see if you can help with my following code failing?

` private async Task ScheduleBroadcastMessageJob(CreateOrUpdateBroadcastMessageInput input, string broadcastMessageId) {

        var currentTicks = DateTime.Now.Ticks;
        var scheduleTicks = input.ScheduleDateTime.Value.Ticks;
        TimeSpan scheduleTime;
        if (input.SendType == BroadcastSendType.Schedule)
            scheduleTime = TimeSpan.FromTicks(scheduleTicks - currentTicks);
        else
            scheduleTime = new TimeSpan(0, 0, 30);
        await BackgroundJobManager.EnqueueAsync<BroadcastMessageJob, BroadcastMessageJobArgs>(new BroadcastMessageJobArgs
        {
            MessageInput = input,
            BroadcastMessageId = broadcastMessageId
        }, BackgroundJobPriority.Normal, scheduleTime);
        
    }`

Error Log

    hi

    This looks like a problem with hangfire, can you provide steps to reproduce the problem.

    Thanks.

    One point i missed was that it works fine if i don't provide this "BackgroundJobPriority.Normal, scheduleTime)"

    Its actually quite simple re-produce.

    BackgroundJobManager.EnqueueAsync's Job which works would stop working if the delay timestamp is provided.

    What version of ABP are you using? What version of the hangfire related package are you using?

    I use ABP's free startup template, which is ABP 5.1.0, and HangFire 1.7.7 does not reproduce the problem you mentioned.

    Thanks for your reply. Got it fixed. There were two HangFire Services was running for two difference branches of the projects. As soon as we stopped all services but one everything start working.
