I found where something is wrong.
Indeed in net_context_get function, I saw that I reached
CONFIG_NET_MAX_CONTEXTS (equal to 10 in my prj.conf).
For your information, I use UBLOX sara r4 driver (on zephyr 1.14.1 as I mentionned in my previous mail) and I wonder if contexts are well managed in this revision, especially when socket is closed ?
There could certainly be a bug in the socket offloading layer for UBLOX Sara R4 (I'm the maintainer for the current modem layer in Zephyr):
Can you open an issue here:
Please include as much information as you can (from this email series):
- Zephyr version: 1.14.1
- Sample used: samples/net/mqtt_publisher
- Firmware version on SARA R4 modem
And add me as "Assignee"
Thanks in advance for your help
And just to add some precision, I work on zephyr 1.14.1.

Objet : [Zephyr-devel] [TCP/MQTT] Connection issue
Hello Zephyr community,
I contact you because I have an issue when I run mqtt_publisher example
I have the following issue when I have multiple mqtt connection/disconnection (through tcp transport_connect function)
[try_to_connect:233] mqtt_connect: -2 <ERROR>
I have this issue after 10 connection/disconnection. The eleventh one is always failing.
As I said you I saw that this is failing when I try to run mqtt_transport_connect(client); in client_connect.
My configuration is the following one :
MQTT (not secured)
Broker on external server (not any issue on this one)
If you have any idea to help me
Thanks in advance
