Are you able to update the channel manually? (using the web browser and the syntax from the api keys tab of your channel)

Glad you got your data stream working again. Since I didn't see any change in behavior in any of my channels, I suspect it has something to do with your system Often network connectivity for devices can be unpredictable. You may be able to add tracking of signal strength into your code.

Its rare but I have heard of devices having long tern connectivity issues, if your code is written to never reconnect, that may be an issue. Most of the times I saw those type of errors, it was fixed in the wifi library. knowing the hardware you are using might help.

One more possibility is that whatever sensor data you are mesuring could have changed. For example, if you were measuring tempuratere, and it got really hot, then you might have an extra character in the temperature that would change the nature of the psot and possible break it. If you share more information about your process, it would help diagnose the issue.

this issue happen again, around 1 hour ago, not only happen for 1 single channel, but all of our channel, we are using wifi and mobile internet for different channek, but it happen to all channel at the same time, we check the connectivity for each device, the connectivity is good

Can you share the channel numbers where you see the issue?
