Cannot link home assistanta [test] action with Google home app

Hi, today I installed Home assistant to freenas jail. I went through instructions and I had few problems. Sometimes when I click to test my new Google action i receive error, but it created action and I can see this in Google home application. The problem is, when i click to link account its not redirect me to login form of my application. Can anybody help me with this?

From a discussion on Discord, the problem is that their system isn’t accessible from the Internet.
