Connection guide
Why does it say I'm offline?
Discord, WhatsApp, Slack, Teams, and most games run their own presence systems. Any of them can claim you are offline while your browser is happily loading the web. Step one is to tell app presence apart from real connectivity.
Presence is not the same as internet access
A chat app may show offline because its websocket dropped, push notifications failed, a workplace firewall blocks the host it depends on, or the service itself is having a bad day.
Check the wider connection
If OnlineCheck reaches the local probe and the public destinations, your connection is alive and the app-specific route is what deserves attention. If reachability is mixed, the misbehaving app is probably one visible symptom of a deeper routing or DNS problem.
What to send support
Copy the report from the check page. It already contains a timestamp, browser signal, latency, jitter, reachability, and browser network hints. Your public IP stays out of the summary unless you tick the box.
Why refreshing the app may not fix it
Presence systems hold a long-lived connection open in the background. When that connection drops, the app can sit on "offline" until it manages to reconnect to its own backend. A regular web page opens a new request each time, which is why a browser check is a handy second opinion.
How to narrow the cause
Run OnlineCheck, then reopen the app on the same network. If reachability is healthy and latency is good, the issue is almost certainly app-specific. If reachability is mixed or jitter is unstable, the app is exposing a broader connection problem that other things will hit next.
