I am using the arduino cloud to create devices and dashboards for my data. I am having alot of issues with getting the data from the devices to arduino.
I keep getting the following message from the device serial port. "Message ack was not received, the message could not be delivered."
On TTN I can see the data transmission, but I also see the following error message. "Fail to send webhook."
Does anyone know what might be wrong? I have a paid cloud account with Arduino, but they seem to ignore support emails.
I have seen that you have multiple devices registered in the TTN, so I want to know if you are facing a problem with every device or only with just one.
For example, for your device eui-a8610a3032348d11 the last message that I see is on 2023-09-18 at 19:18:54 UTC. Did you disconnect this device? Eventually, could you reconnect it, please?
Yes, I have 12 devices. I do have problems with all of them from time to time. I find I need to reset them many times to get them to connect. Example, that board you saw with message sent was 1 of 4 boards I had running, I reset the other 3 boards several times trying to get them to connect, they all seemed to connect, but were not able to get a message sent with success. I will be back in office tomorrow and can get all 4 of them powered up again and will just leaving them running.
I just connected to the board and reset it. See attached pictures. Everything looks ok on TTN, but I did see "Message ack was not received, the message could not be delivered" on the serial port of the board.
I did a screen shot of the board serial port, the device and gateway on TTN.
@tlampher
i cannot see any application message in your screenshot. Selecting your end-device on the thing stack portal you should see something like this:
Correct. That is what I am seeing. I left that board connected the rest of the day and saw nothing from it and on the serial port of that board I kept seeing that same error message. The 2 other boards I was able to reset and both of those seemed to connect back up without issue. So yesterday 2 of the 4 worked and 2 didn't. I have not found anything different between them.
The 2 boards that were not working yesterday are the 2 that I added this year. I added the devices in the Arduino cloud and when I attached them to my thing, neither one of them filled in the secret tab info, I had to manually add those. I got that info by looking at them on TTN and filled the info in on Arduino from there before I uploaded the sketch to the boards.
Could that be an issue? That was the first time I have ever had to do that though and I have had these issues since I started using them last year. I have not been able to figure out the cause and it seems this issue can be with any boards.
@tlampher th error: "Message ack was not received, the message could not be delivered" is al LoRa level so i suspect something is not working between your board and your gateway.
What happens if you try to connect only one board at time? Do you see any "Forward uplink data message" from your board to your gateway?
Today I am just running the one board that I know is an issue board. The gateway they are connected to is in my office. I have the same results with the other gateway that is in the field.
Here is the code....

float co2;
float humidity;
float o2;
float temp;
int co2base;

Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.

I removed the both delays that were in my loop and have the same results. Get same message on serial port and see nothing on TTN after the initial connection.
I need to take back what I said. I had a few more delays in the loop that I missed. I now removed those and now that those are removed it will not connect at all. I just keep seeing failed to connect retrying in 500ms on the serial print out now.
