Fix NewConnectionError

✅ Solution

NewConnectionError in telegram-bot-api usually signifies that your bot cannot establish a connection to Telegram's servers, commonly due to network issues or an incorrect bot token. Verify your internet connection and ensure that the bot token in your code is correct and that you don't have any firewall rules blocking the traffic. If the issue persists, consider using a proxy server or VPN if Telegram is blocked in your region.
