Youtube streaming on OBS is disconnected every hour.

[Tom-K]

We are having trouble with OBS's Youtube transmission being disconnected on an hourly basis.
At the time of the trouble, OBS is still transmitting, but Youtube is actually terminated.
And without fail, the transmission disconnects itself at one hour intervals.
Sometimes it is exactly one hour, sometimes it is exactly two hours, and sometimes it is exactly three hours.
I have no idea what the difference is between when it cuts off and when it does not.
The mission timer function is set to off, so that function does not seem to be involved.
There is no error and there is no information in the logs.
Does anyone have any details on this?

After turning off the delivery timer, reviewing the MTU values, and reinstalling OBS, the symptoms did not go away, so we reverted to the previous version of OBS, 30.2.2, and the disconnections stopped.
It may be due to our environment, but there may be something wrong with the latest version.

Distribution site: Youtube - HLS (HDR, 1080p, 60fps)
Version of OBS used: 30.2.2 (30.2.3 when the trouble occurred)

I'm having exactly the same problem.
After about 1 hour of streaming to YouTube, my live stream ends. It always happens around 1 hour.
I just can't find an explanation for this.
I'm using the 30.2.3 version.

In a way, I was relieved to find someone else suffering from similar symptoms.
I thought it was only happening in my PC environment.

I had been stable on 30.2.2 for a while,but,
Unfortunately, today another one-hour disconnection occurred.
I have no choice but to downgrade my OBS further and am observing the progress.
I will post in this thread if I find out anything.

Please read the pinned posts on this forum.

”Dropped frames/disconnecting/lag? Read this first!”
I have read through this thread in advance.
However, I have not been able to determine the cause of this phenomenon, “or some reason, the streaming sometimes stops every hour.”
Therefore, we are seeking expert opinion.
Why is there always a disconnection every “1 hour = 60 minutes”?
I think there may be a clue to this phenomenon in the “hourly” increments.

Keep on it. You can do it. Read the second pinned post.
Is not that hard. Just read it.

And there's more pinned posts too.

All fixed posts are read through.
Unfortunately, this phenomenon could not be solved by the solution in the fixed posts.
The trouble is that the error does not remain in the OBS log file.
Indeed, even though it is disconnected, the log shows that the delivery is still in a continuous state, and OBS recognizes that it is running normally.
Therefore, the log file is useless in this case.
There is a possibility that the problem may be on the Youtube side, and I am now beginning to suspect that this is the case.

Great. Good to know you have no issue at all on the OBS side.

I just tried 3 hours over of live streaming and the disconnection phenomenon does not seem to occur when using RMTP stream keys for streaming on Youtube.
This may only happen with HLS stream keys.
However, this is not a valid solution as it would mean that the streaming I want to do is impossible as I would not be able to stream in HDR.
I am sorry that I cannot try this in OBS because switching to HLS stream key disables the “Settinngs>Advanced>network” setting, but I am thinking that perhaps if it is possible to switch to IPv4, it might be stable.

This is an issue with the last two new versions of OBS. The two versions below the issue does not occur every 1 hour of streaming.
I looked at all the pinned topics and reviewed my entire network, there is nothing wrong. The disconnection only happens every hour with the last two versions of OBS.
