How to get around this Faraday::ConnectionFailed error?

Question

ruby

There is a simple code. Every 10 seconds it sends an http request and receives a response.

require 'vk-ruby'

app = VK::Application.new(app_id: ------, version: '5.71', access_token: '--------------------')

check = 0
while true
    get = app.vk_call 'messages.getDialogs?count=2'
    body = get['items'][0]['message']['body']
    
    if body != check
        p body
        check = body
    end
    
    sleep 10
end

But occasionally an error occurs and the program closes.

How can this situation be resolved? Or is it possible to set a condition, if this error occurs with the connection, then wait another 10 seconds and repeat the request. How to implement?
