[BUG] Irregular speedtest fail

Start with the speedtest-tracker Docker service configuration and its scheduled-run container logs, comparing the successful ping entries with runs that report connection refused or network unreachable. Determine whether the intermittent failure is reproducible in the described hourly Docker setup; done means scheduled tests complete consistently without those errors.

Is there an existing issue for this?

Current Behavior

I have been getting some fails on speedtests without any clear indication why. Getting the following error:
Error: [111] Connection refused | Error: [0] Cannot read from socket: | Error: [101] Network unreachable

Expected Behavior

Expected is to have all tests complete

Steps To Reproduce

1. Run the app in docker environment
2. Run test hourly
3. Sometimes test passes, sometimes it does not

Environment

- OS: Ubuntu 24.04.4 LTS
- How docker service was installed: Through apt
