monitor type ping stopped working

Info Uptime Kuma Version: 1.3.2 Using Docker?: Yes OS: Windows (client) Docker with uptime-kuma runs on Debian 10 Browser: Chrome

I installed uptime-kuma a few days ago and setup a few monitors, most of them https and one as ping type. The ping type one stopped working yesterday evening. I know the target is up, even if I do a docker exec -ti uptime-kuma sh and do a manual ping to the same target the ping works so why does it keep failing for a full 24h inside uptime-kuma?

Also, uptimerobot reports no issues pinging this particular host.

Open for any suggestions.

Just wanted to let you know, that I have now added fixed DNS servers to uptime-kuma’s docker-compose.yml file

    dns:
      - 1.1.1.1
      - 9.9.9.9
      - 8.8.8.8

Response times have gone seriously down compared to before. Before this, the docker host used to use a locally (Docker run) DNS (adguard home).

Thanks, I have switched to :1.5.2-debian and everything seems fine. I guess I’ll check in a few weeks later and figure out how you are handling tags. For now I’ll keep using 1.5.2-debian - maybe later you’ll have a generic :debian or whatever.

If Debian is better for most users, I will use Debian as main tag in the future. For example:

• 1.6 (Debian)
• 1.6-alpine (Alpine)
