After some time, the bot stops responding

[fishkaoff]

When I launch the bot, it works well, but if I don't send messages to it for a while, it stops responding. Moreover, every time after a different time, sometimes 10 minutes, sometimes an hour. I want to note that the message reaches him by logs, but he does nothing.

code: bot.go:

  func (b *Bot) StartBot() {
    updateConfig := tgbotapi.NewUpdate(0)
    updateConfig.Timeout = 60
    updates := b.Api.GetUpdatesChan(updateConfig)
    log.Printf("Authorized on account %s", b.Api.Self.UserName)
    b.handleUpdates(updates)
  }

handleUpdatesFunction:

    func (b *Bot) handleUpdates(updates tgbotapi.UpdatesChannel) {
    for update := range updates {
        if update.Message != nil && !update.Message.IsCommand() {
            b.HandleMessage(update)
            continue
        }
        if update.Message != nil && update.Message.IsCommand() {
            b.HandleCommand(update)
            continue
        }
        if update.CallbackQuery != nil {
            callback := tgbotapi.NewCallback(update.CallbackQuery.ID, update.CallbackQuery.Data)
            if _, err := b.Api.Request(callback); err != nil {
                panic(err)
            }
            b.HandleCallback(update)
        }

    }
}

terminal when bot is not responding:
