Before you start

Message sync, file transfers, Huddles and workspace SSO use different connections.

Step by step

  1. Check the official status or announcement page at https://slack-status.com/. A help page is not necessarily a live status monitor.
  2. Reproduce the Slack issue on one exit and record its time, code, stage and duration.
  3. Send a short message, then test a small file and a call. Use Slack’s built-in connection test.
  4. Compare wired, Wi-Fi or another network while changing only one condition.
  5. If the app is slow but the browser works, compare app and system proxy settings for duplication.
  6. Message sync, file transfers, Huddles and workspace SSO use different connections.

Common questions

Can switching networks fix every Slack error?

No. Account privileges, subscriptions, file permissions and service outages require separate checks.

What should I send to support?

Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
