Is Slack Down? Live status & outage reports

Service info and troubleshooting

Messages Not Sending or Stuck

If a message just spins and never delivers, the first thing to check is your internet connection — open any website to confirm it's actually working. If the connection is fine, try refreshing the app or restarting it entirely. On desktop, quit Slack fully and relaunch it. On mobile, close the app from the task switcher and open it again. If the problem persists, check whether the issue is specific to one channel or workspace — sometimes a single channel cache gets corrupted and clearing it fixes things.

Files and Media Won't Upload

Large file uploads often stall when your connection is unstable. The platform has a 1 GB file size limit per upload, so anything beyond that will silently fail. Try uploading from a different network or switching from Wi-Fi to a wired connection. If uploads consistently fail regardless of file size, clear the app cache: on desktop go to Help → Troubleshooting → Clear Cache and Restart.

Notifications Not Arriving

• Check your notification settings inside Slack under Preferences → Notifications — make sure Do Not Disturb isn't active.
• On iOS and Android, verify that system-level notification permissions are granted for the app.
• For desktop, confirm that Slack isn't blocked by your OS focus or quiet hours mode.
• If you're missing only certain messages, check channel-specific notification overrides.

App Freezes or Loads Slowly

Slack's desktop client is Electron-based, which means it can get sluggish over time — especially if you're in many workspaces or have a lot of channels open. The quickest fix is clearing the cache via Help → Troubleshooting. If freezing happens regularly, check how much RAM Slack is consuming in Task Manager or Activity Monitor. Limiting the number of open workspaces and disabling animated emoji (Preferences → Accessibility) noticeably reduces resource usage.

Can't Log In or Session Keeps Expiring

• Make sure you're entering the correct workspace URL — it's your-workspace.slack.com, not just slack.com.
• If SSO is involved, the issue might be on your organization's identity provider side, not Slack itself.
• Try logging in via a private browser window to rule out cookie or extension conflicts.
• If the session keeps dropping, check that your system clock is accurate — token validation fails when time is significantly off.
