Guest machine can't connect to host machine

[lzontar]

Hello, on the image below you can see the error that my 'vagrant up --provider azure' throws and I have absolutely no idea why. If needed I can also provide the output of 'vagrant up --provider azure --debug'. Could someone please tell me how to set up networking properly on guest machine through Vagrantfile?

My Vagrantfile:

require 'vagrant-azure'
Vagrant.configure("2") do |config|
  config.vm.box = 'azure'
  config.vm.box_url = 'https://github.com/azure/vagrant-azure/raw/master/dummy.box'

  config.vm.network "private_network", guest: 80, host: 80

  config.ssh.username = 'vagrant'
  config.ssh.private_key_path = '~/.ssh/id_rsa'

  config.vm.synced_folder '.', '/vagrant', :disabled => true

  config.vm.provider :azure do |azure, override|
    # each of the below values will default to use the env vars named as below if not specified explicitly
    azure.tenant_id = ****
    azure.client_id = ****
    azure.client_secret = ****
    azure.subscription_id = ****
#ENV['AZURE_SUBSCRIPTION_ID']

    azure.tcp_endpoints = '80'

    azure.vm_name = 'grafmuvivm'
    azure.vm_size = 'Standard_B1s'
    azure.vm_image_urn = 'Canonical:UbuntuServer:18.04-LTS:latest'
    azure.resource_group_name = 'grafmuvirg'
    azure.location = 'westeurope'
    virtual_network_name = 'grafmuvivm-vagrantPublicIP'
  end

  # Declare where chef repository path
  chef_repo_path = "./chef"

  # Provisioning Chef-Zero
  config.vm.provision :chef_zero do |chef|
    # Added necessary chef attributes
    chef.cookbooks_path = 'chef/cookbooks'
    chef.nodes_path = 'chef/cookbooks'

    #### Adding recipes ####
    chef.add_recipe "api::ssh_user"
    chef.add_recipe "api::grafmuvi"

    # Running recipes
    chef.run_list = [
      'recipe[api::ssh_user]',
      'recipe[api::grafmuvi]'
    ]
    # Accept chef license
    chef.arguments = "--chef-license accept"
  end
end
