How to set up vpn for telegram bot in java?

Question

Java

When you start a simple bot (the bot writes in response what was written to it), the following falls

Как я понимаю это проблема блокировки..Если я ошибаюсь подскажите пожалуйста в чем дело и как исправить.

Answer 1

I do not write in Java, but the error is clearly due to connection problems. When developing, your solution will be to sit through a VPN, and just use a foreign server. Although, on many Russian hostings, everything is in order with the telegram. There is no need to insert a VPN inside the bot itself, it is pointless and creates only problems.

Answer 2

I agree with Anton Neverov If you develop locally, you turn on vpn on your PC, you buy a server either abroad or Raschke, if I don’t block the cart.

Answer 3

I downloaded the same lib, but there, in the example, classes are used that are not in it.
For example, these:

import org.telegram.telegrambots.meta.logging.BotLogger;
import org.telegram.telegrambots.meta.logging.BotsFileHandler;
import org.telegram.updateshandlers.*;

didn't you have that problem?
