Before you start

Sign-in codes, message sync and media downloads are separate checks; client proxy settings may differ.

Step by step

  1. Check the official status or announcement page at https://telegram.org/. A help page is not necessarily a live status monitor.
  2. Reproduce the Telegram issue on one exit and record its time, code, stage and duration.
  3. Compare in-app and system proxy settings for duplication. Never forward a sign-in code to another person.
  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. Sign-in codes, message sync and media downloads are separate checks; client proxy settings may differ.

Common questions

Can switching networks fix every Telegram 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.
