Description:

Hello,

I’m experiencing an issue with the Netbird service on my device. After the service has been running for a while, it fails to connect to the MQTT server at mqtt.xxxx.ai at the same time I can connect the device. This problem occurs intermittently, and a restart of the Netbird service temporarily resolves the issue.

Details:

Devices: Raspberry Pi Zero W

Netbird Versions:
Daemon version: 0.28.7
CLI version: 0.28.7

Network Configuration:

Working Device:
NetBird IP: 100.116.136.203
Connectivity to mqtt.xxxx.ai is successful initially.

Non-Working Device:
NetBird IP: 100.116.106.3
Fails to ping mqtt.xxxx.ai after some time.

Network Routes:

Working Device:
default via 192.168.1.1 dev eth0 proto dhcp src 192.168.1.195 metric 100
default via 192.168.1.1 dev wlan0 proto dhcp src 192.168.1.188 metric 600
100.116.0.0/16 dev wt0 proto kernel scope link src 100.116.136.203
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.195 metric 100
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.188 metric 600

Non-Working Device:
default via 192.168.16.1 dev eth0 proto dhcp src 192.168.16.114 metric 100
100.116.0.0/16 dev wt0 proto kernel scope link src 100.116.106.3
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
192.168.16.0/24 dev eth0 proto kernel scope link src 192.168.16.114 metric 100

Steps to Reproduce:

Start the Netbird service on both devices.
Monitor connectivity to mqtt.freshsens.ai over time.
Observe that after some time, the non-working device fails to connect to the server.
Restarting Netbird on the non-working device temporarily resolves the issue.

Expected Behavior:

Both devices should consistently be able to connect to mqtt.xxxx.ai without requiring a restart of the Netbird service.

Additional Information:

Restarting the Netbird service resolves the issue temporarily.
The problem seems related to the handling of network routes or connectivity after prolonged uptime.
I would appreciate any assistance or suggestions for resolving this issue.

Thank you!
