Since a few months, I’ve been working on sending variables to Ubidots for a project via a python script with Paho MQTT. Code was functioning properly but since last month, with the same code, I have a erratic behavior on Ubidots where I send variables. Nothing seems to be received by Ubidots, or one in 10 minutes, one in 2 hours, never receiving or receiving every packets sent.
By looking in wireshark, I can see packets sent to Ubidots and what seems to be response from Ubidots to this packets. And in the script when I enable logs, I can see PUBACK from my messages which gets me confused.
I thought that maybe a problem with my internet connexion could be responsible somehow but after I tried multiple sources (wifi, ethernet, 4G network), problem is still there.
I tried simpler codes like http://help.ubidots.com/developer-guides/connect-to-ubidots-mqtt-broker-with-tls-security (without ssl implementation), but it remains the same.
My biggest concern is that connexion to Ubidots seems to work, subscribing too (I’m receiving variables of subscribed topics) but when it tries to publish, it has this issue.
Is there anybody that have experienced this or could have an idea what can cause it?
