If Telegram is not working, first check whether your internet connection or Telegram’s service is the problem, then restart the app and update it. For messages that will not send, login trouble, or crashes, the right fix depends on what is failing; work through the checks below in order.
Check whether Telegram or your connection is down
Open a few unrelated websites or apps on the same device. If they also fail, troubleshoot Wi-Fi or mobile data before changing Telegram settings. Switch between Wi-Fi and cellular data, if available, and briefly turn Airplane Mode on and off to reconnect. If other services work but Telegram does not, a temporary service disruption, app issue, or network restriction is more likely.
Telegram does not provide a single public status indicator that can diagnose every outage. Check Telegram’s official announcement channels or support information using a service you can access, and compare reports from other users cautiously: social posts may be delayed or inaccurate. If many people report the same problem, waiting and trying again later may be the only useful step. Avoid downloading an unofficial “fix” or logging in through a site that asks for your Telegram code.
Try these basic fixes first
Use this sequence before making changes that could affect local data or account access:
- Close Telegram completely and reopen it. On a phone, remove it from the recent-apps view; on a computer, quit the application rather than merely closing its window.
- Restart the device. This can clear a temporary network or app process problem.
- Update Telegram from the official app store or Telegram’s official desktop download source. Update your device’s operating system if a pending update is clearly relevant.
- Check that the device has free storage and that its date and time are set automatically. Very low storage can interfere with downloads or app behavior, while a badly incorrect clock can cause connection problems.
- Try Telegram on another device or in Telegram Web, using the official site. If it works there, the issue is probably limited to the original app, device, or network.
Do not uninstall the app as your first step. Telegram’s cloud chats generally sync after you sign in again, but secret chats are device-specific and are not stored in Telegram’s cloud. Removing the app or clearing its data can also remove locally stored files or require a fresh login.
Fix messages that will not send or arrive
A message showing a sending indicator may be waiting for a connection. Check whether other apps can access the internet, then switch networks and reopen Telegram. If only one conversation is affected, consider whether you can still view the person’s profile and send messages elsewhere. A recipient’s privacy settings, a blocked account, or a restriction on the account may affect a particular chat; repeatedly reinstalling the app will not resolve those cases.
For missing new messages, open the relevant chat and pull down to refresh where the app supports it. Check whether the conversation is archived, muted, or hidden in a folder. Notifications can fail even while messages arrive normally, so send yourself a test from another account or ask a contact to message you before assuming delivery is broken.
On phones, review the device’s notification settings for Telegram, including permission to show alerts and any Focus, Do Not Disturb, or battery-saving mode. Telegram also has notification controls within its settings, and an individual chat can have its own mute setting. Menu names vary by operating system and app version, but check both the device and app; enabling alerts in only one place may not be enough.
Resolve login codes and account access issues
Telegram may send a login code to an already signed-in Telegram session instead of by SMS. Check the app on your other logged-in devices before requesting another code. Enter the latest code exactly as provided, and do not share it with anyone—not even someone claiming to be support. Telegram support will not need your login code or your two-step verification password to troubleshoot an app problem.
If you cannot receive a code, confirm that the phone number is entered with the correct country code and can receive calls or text messages. Follow the options shown in Telegram rather than repeatedly requesting codes, which can lead to delays or temporary limits. If two-step verification is enabled, you will also need its password after the code. Use Telegram’s official recovery flow if you have forgotten it; do not trust third-party recovery services.
If you still have access on another device, review active sessions in Telegram’s Privacy and Security settings and end sessions you do not recognize. This is a sensible account-protection step after an unexpected login alert, but it is separate from ordinary connection troubleshooting.
When Telegram crashes, freezes, or will not open
First restart the device and install available updates. On Android, you can usually clear an app’s cache through Telegram’s storage settings or the system’s app settings; labels vary by device. Clearing cache removes temporary files, not the same thing as clearing app data. Avoid selecting “clear data” or “clear storage” unless you understand that it may sign you out and remove local content.
On iPhone or iPad, force-close and reopen the app, restart the device, and check for app and system updates. If Telegram crashes immediately after opening, free some device storage and try again. On a computer, quit other resource-heavy applications, restart Telegram, and check for updates from the official source. If a recent update appears to have triggered the problem, report it through official support rather than installing an unknown older build.
Reinstalling is a later option, not a universal fix. Before doing so, make sure you can access the phone number on the account and any required two-step verification password. Remember that secret chats do not sync between devices, and locally downloaded files may need to be saved separately.
Check network restrictions and proxy settings
Some workplace, school, public, or regional networks restrict messaging services. Compare Telegram over a trusted different connection, such as your home Wi-Fi or mobile data. If it works on one network but not another, ask the network administrator whether access is restricted rather than trying to bypass their controls.
Telegram includes proxy settings, but a proxy can also cause a connection to fail. If you previously configured one, check Telegram’s Data and Storage or connection settings and disable it temporarily to test. Do not enter proxy details from an untrusted source: the operator may be able to observe connection metadata, and an unfamiliar configuration could expose you to privacy risks. A proxy is not required for ordinary use on a network that already allows Telegram.
Frequently Asked Questions
Why is Telegram stuck on connecting?
Check whether other apps can use the internet, switch between Wi-Fi and mobile data, and restart Telegram. If it fails only on one network, that network may be blocking or interrupting the connection.
Why are Telegram messages not sending?
A weak or restricted connection is a common cause. Reconnect, try another network, and check whether the problem affects every chat or only one. A recipient’s settings or an account restriction may affect an individual conversation.
Will reinstalling Telegram delete my chats?
Regular cloud chats normally return when you sign in, but secret chats are device-specific and do not sync through the cloud. Reinstallation can also remove local files and require you to log in again, so try less disruptive fixes first.
Why am I not getting a Telegram login code by SMS?
Check other signed-in Telegram sessions because the code may appear there first. Verify the phone number and country code, then follow the available in-app instructions. Never give the code to another person.
Telegram works, but why are notifications missing?
Check notification permission and quiet modes in your device settings, then check Telegram’s notification settings and the individual chat’s mute status. Messages may be arriving even when alerts are suppressed.
