Recurring page reloads on Grafana dashboards, getting 'Network Error' and 'Unauthorized'

Grafana Dashboards
,

Recently updated to v10.2.3 (1e84fede543acc892d2a2515187e545eb047f237) and currently having trouble with the browser reloading the page at fixed intervals. Intervals are sometimes almost exactly 1 hour, sometimes 20 minutes. I have not changed any configurations, only updated the image used in my Docker container.

The error looks as follows:

  1. Everything works fine.
  2. Suddenly, 2 notifications pop up: “NetworkError when attempting to fetch resource.” and “Unauthorized.”
  3. 1 second later, barely enough time to read the notifications, the browser reloads the page.
  4. The dashboard loads normally, no login needed.
  5. This will repeat at fixed intervals; I have observed 1 hour and 20-minute intervals.

What I tried:

  • Cleaned browser cache, cookies, and data.
  • Checked login_maximum_inactive_lifetime_duration and login_maximum_lifetime_duration, which are not set, so default values are active, which are something like 30 days.

The error occurs in Firefox; I’m not sure if other browsers are impacted as well, as I do not use Chromium-based browsers.

Since the error is persistent, I reverted to version 10.1.6, and the issue seems to be gone. Not really a solution though.

I’m experiencing this issue too, ever since upgrading to 10.4 and now 11.0

Pretty standard install and usage I’d think. Anything I should look into?

We had a similar issue; a logout seems to fix it. You can hit the URL directly https://grafana../logout

In our case the firefox plugin “µBlock Origin” was the culprit.

Disabling the plugin for the grafana website solved the problem. Still unclear what exactly caused it.
