Connect Telegram in three steps
Select SOCKS5
On Desktop, open Settings, Advanced, then Connection Type. On Android, open Settings, Data and Storage, then Proxy Settings. Menu wording may vary by version. Select SOCKS5 for a Databay connection.
Enter the proxy fields
Copy the server and port from the dashboard and enter proxy authentication when required. Do not paste a complete connection URL into the hostname field or choose an MTProto secret field.
Test from your actual network
Enable the proxy and check Telegram’s connection state. If it fails, test the host and port from the same device network, then check credentials. A test elsewhere does not prove reachability from your connection.
Four fields, one SOCKS5 connection
A field map, not working credentials. Copy actual values from your dashboard.
Keep the server, port, and credentials in separate fields. A Telegram login code belongs only in Telegram’s account flow, never in the proxy password field.
What to measure: a successful app connection
First establish server reachability and authentication, then confirm Telegram connects. A checker result alone does not prove the route will work for Telegram from every ISP or country.
Choose a Proxy Type Telegram Actually Supports
Telegram's official proxy guide documents two in-app choices: SOCKS5 and MTProto. SOCKS5 takes a server, port, and optional username and password. MTProto takes a server, port, and secret. They are different protocols, so an MTProto secret cannot be pasted into SOCKS5 fields and a SOCKS5 username cannot be used as an MTProto secret.
Databay supplies authenticated HTTP proxying, HTTPS CONNECT tunnelling, and SOCKS5 access. For Telegram, select SOCKS5; Databay does not sell an MTProto proxy. Copy the gateway host, port, username, and password from the dashboard, and keep the credentials out of screenshots or shared links. If you only have an HTTP proxy, it is not the in-app Telegram route described by Telegram's documentation.
Configure a Telegram Desktop Proxy on Windows
In Telegram Desktop, open Settings → Advanced → Connection type, choose to use a custom proxy, and select SOCKS5. Enter the server and port exactly as issued. Add the username and password when the endpoint requires authentication, save the entry, and enable it. Telegram's status indicator should change from connecting to connected; if it does not, stop and diagnose the route rather than cycling through credentials blindly.
Run a preflight before placing the endpoint in Telegram. Put the same host, port, protocol, and credentials into the Databay proxy checker to separate endpoint reachability from a Telegram configuration error. A successful checker result proves only that one probe reached the proxy at that time. It does not prove that Telegram is reachable from every network or that a public endpoint is trustworthy.
Set Up a Telegram Proxy on Android
On Android, Telegram documents the path as Settings → Data and Storage → Proxy Settings. Tap Add Proxy, select SOCKS5, and enter the same four connection fields: server, port, username, and password. Save the entry, turn on Use Proxy, and wait for the connected state before sending messages or starting a call. Menu wording may differ slightly by app release, but the protocol and fields should remain recognizable.
Keep one variable fixed while troubleshooting. Test the endpoint outside Telegram first, then compare the server and port character for character, then re-enter the credentials. Do not switch countries, session modes, passwords, and protocols in the same attempt: that makes a timeout impossible to localize. For iOS, Telegram places the equivalent control under Settings → Data and Storage → Proxy.
Choose a Telegram Proxy for Iran Without Guessing
A Telegram proxy for Iran first needs a gateway that the user's current network can reach. Exit country is a separate decision: choose it for the service geography and latency your authorized use needs, not because a marketing label calls one country universally best. A nearby exit may reduce round-trip time, while a farther exit may be appropriate when the account or service legitimately operates in that region. Availability can change by access network, so no provider can guarantee one route works everywhere in Iran.
For an account session, prefer a stable residential or mobile route over changing connections or sessions. Databay rotation is connection- and session-bound; no fresh IP is promised for each request. Databay sticky sessions request the same exit for a defined window, which avoids changing the apparent network path during one login session; they do not guarantee that the underlying carrier path or Telegram availability will remain unchanged. Compare the available network classes on the proxy network overview, then test the chosen endpoint from the actual connection that will use it. Follow local law and Telegram's terms.
What a Free Telegram Proxy Can and Cannot Do
A free Telegram proxy is useful for a disposable reachability check, but public endpoints can disappear, change operators, become overloaded, or expose credentials supplied at the proxy layer. Telegram warns users to obtain proxies from trusted sources because a proxy operator can observe the IP address connecting to it. Telegram also explains that app traffic remains encrypted; that does not make an unknown operator suitable for a sensitive account.
If you need a free proxy active today, filter the live proxy list for SOCKS5, note its last check time and latency, and probe it again immediately before use. Never interpret “active” as safe, private, or durable. For recurring access, use an authenticated managed endpoint with an accountable operator, rotate the password if it has been exposed, and keep a direct fallback for account recovery.
Diagnose Connection Failures at the Right Boundary
A timeout usually means the client did not complete a network connection to the gateway or through it. Check whether the hostname resolves, whether the port is reachable from the same device and network, and whether a local firewall or access network blocks that path. Connection refused generally means something answered at the host but no proxy service accepted that port. An authentication failure means the endpoint was reached but rejected the supplied credentials.
If the proxy checker succeeds and Telegram still cannot connect, confirm that SOCKS5, rather than HTTP or MTProto, is selected and re-enter the fields without a URL scheme. Then try the same documented setup on another authorized network to separate a local access problem from an endpoint problem. A destination refusal, challenge, or policy notice is a stop condition: a new proxy does not create permission to bypass a service control.
Use the Telegram Proxy Link Format Carefully
Telegram documents a SOCKS link in the form https://t.me/socks?server=<server>&port=<port>&user=<user>&pass=<pass>. Opening it can prefill the proxy screen, which is convenient for a public endpoint. It is a poor way to distribute a private managed password: the credentials become part of a URL that may enter chat history, browser history, analytics, screenshots, or logs.
For a Databay route, enter credentials directly in Telegram or transfer them through an approved secret manager. If a credential-bearing link was shared, revoke or rotate that password. The proxy format converter can help separate an endpoint into host, port, username, and password locally in the browser; it does not contact the proxy or save the entered string.
When the result looks wrong
Telegram stays on Connecting
Protocol, port, authentication, or network reachability may be wrong.
Next step: Verify SOCKS5 and separate field values, then test from the same network.
The proxy works elsewhere
Your current ISP or network may treat the endpoint differently.
Next step: Compare the connection from the affected network and record the time of the failure.
A free endpoint stops responding
Public endpoints can disappear or change ownership.
Next step: Retest before use and choose an operator you trust; do not publish credential-bearing proxy links.
