Balena Dashboard - Logs Visibility Issue

Product support balenaOS
1

Hi team,

I’m unable to see any logs on the Balena dashboard for the last few days - it’s just displaying “No Logs yet.” This is unusual since everything was working properly when I checked on Friday.

I’ve already verified the Balena status page (https://status.balena.io/), which indicates all systems are operational.

Has anyone else noticed this issue with the logs, or is it only affecting me?

Hi @terry-cpi , we haven’t had any other reports of this yet, so it might be something local to your device. Does this behaviour persist over reboots? Also if you start a terminal session into the hostOS and list your containers with balena ps and then run balena logs <YOUR_CONTAINER_ID> do you see the device writing logs?

Finally, it would also be good to look at the supervisor logs for any errors, this can be done by running journalctl -u balena-supervisor --no-pager . It could be that for some reason the supervisor can’t connect to the logging backend because of a DNS issue or something similar.

Hey @shaunmulligan1, when I pushed a new release, I initially saw logs appearing on the dashboard. However, after a few hours, they stopped displaying. Despite this issue, I can still view logs using the command balena logs <YOUR_CONTAINER_ID> via CLI.

Hi @terry-cpi, to me it seems that the issue you’re experiencing may be caused by a few different factors, such as an ad blocker or a network rule blocking streaming requests. Ad blockers like uBlock and Adblock often block streaming endpoints, especially those that include query parameters like stream=1, which we use for real-time logs.
A few steps you could take to troubleshoot:

  • try a different browser to check if a browser extension (such as an ad blocker) is interfering with the request.
  • try a different network, such as mobile tethering, which typically has fewer restrictions. This can help rule out the possibility of a firewall blocking the request to
    https://api.balena-cloud.com/device/v2/<DEVICE_UUID>/logs?count=100&stream=1
  • If you’re using an ad blocker, please add an exception to allow all requests to api.balena-cloud.com to ensure the logs can stream without interference.

Let us know how it goes after trying these steps
