What do error codes like 404/420 mean when Telegram says Unable to connect to server?

In the digital age, communication apps like Telegram have become an integral part of our lives. However, encountering error codes such as 404 or 420, especially when Telegram displays the message Unable to connect to server, can be quite frustrating, especially for users in overseas regions. This article delves into the meaning behind these error codes and the implications they hold for Telegram users globally.

Understanding the 404 Error Code

Definition of a 404 Error

A 404 error, also known as a Not Found error, is a standard HTTP status code indicating that the server cannot find the requested resource. In the context of Telegram, this means that the server is unable to locate the specific message, file, or user you are trying to access.

Possible Causes of a 404 Error

1. Incorrect URL: Typing an incorrect URL or a misspelled username can lead to a 404 error.

2. Deleted Content: If the content you are trying to access has been deleted, you will encounter a 404 error.

3. Server Glitches: Sometimes, server-side issues can cause a 404 error, even when the content exists.

Deciphering the 420 Error Code

What is a 420 Error?

A 420 error, also known as Bad Gateway, is an HTTP status code indicating that the server, while acting as a gateway or proxy, received an invalid response from an upstream server. This error is more specific to Telegram and can occur when there is a problem with the app's connection to its servers.

Common Causes of a 420 Error

1. Network Issues: Poor internet connectivity or a firewall blocking Telegram traffic can lead to a 420 error.

2. Server Overload: If the Telegram servers are experiencing high traffic, it can cause a 420 error.

3. Outdated App: An outdated version of the Telegram app can also trigger a 420 error.
