What are the common errors when using a proxy with Telegram

Common Errors

1. Connection Failure: Users often experience difficulties connecting to Telegram when behind a proxy, especially if the proxy restricts direct IP access. This can manifest as the application failing to connect or hanging during the connection process[2][4].

2. Slow Performance: Using a proxy can introduce latency, resulting in slower speeds. This is particularly noticeable when the proxy server is overloaded or if the connection is not optimized for Telegram's requirements[1][3].

3. Incompatibility with Features: Certain features, such as voice calls, may not function correctly when using a proxy. Users have reported that calls remain stuck on "exchanging keys" or simply do not connect at all, indicating that the proxy may not support all Telegram functionalities[4][5].

4. Security Risks: Free or unreliable proxies can pose significant security risks. Data transmitted through these proxies may be vulnerable to interception, leading to potential privacy breaches. It is advisable to use reputable proxy services to mitigate these risks[1][3].

5. Outdated Proxy Settings: If a manually configured proxy becomes outdated or blocked, users may lose access to Telegram. Regularly checking and updating proxy settings is essential to maintain connectivity[5].

6. Firewall Restrictions: Firewalls may block the ports used by Telegram or the proxy, preventing the application from functioning correctly. Users need to ensure that the necessary ports are open and configured properly in their firewall settings[4].

By being aware of these common errors, users can better troubleshoot issues when using a proxy with Telegram and enhance their messaging experience.
