I’ve started using TTNv3 last month. I’ve set-up a simple python script with paho.mqtt on my server to retrieve the data from my temperature sensors (10 of them) using MQTT protocol. It runs in the background. It works perfectly fine until the update to V 3.13.0 on May 21. I’ve stopped receiving uplink messages despite the fact that I can see my gateway and my sensors are online and working well.
Nothing has changed on my side since the beginning of the month and I can’t figure what is different regarding MQTT for the TTN after reading the log for the update 3.13.0.
So far, I’ve tried :
Rebooting my server (and my script obviously)
Test the connection. I can see in my script that the connection is established when I run it. I also have the confirmation message in the TTN console, so everything looks fine on this side. I can also see in the TTN console “receive uplink”, “forward uplink” and “forward data message to application server”. However, there are no uplink messages appearing in my log on my server.
Reset the API Key
I’ve been trying for hours to reconnect/disconnect to see if the problem would resolve and I finally got it working without any change to my script, so I guess it wasn’t the problem. However, I was testing it in the foreground, so I’ve stopped it and restarted it in the background and I have the same problem now, no uplink messages on my server despite everything else showing it should work.
I’ve also tested it on my desktop to see if my server was the problem and I had the same behaviour (both are Debian based Linux distro).
I’ve waited a bit and did some more testing, and I’ve finally managed to get a connection and data for a couple of hours yesterday, but it silently fails after a few hours (both on my desktop and server).
I’m in Canada using the nam1.cloud. Am I the only one experiencing this issue? I’m unsure what to look at for debugging purposes, since it’s an intermittent issue.
