I'm using Kamal (old MRSK) with Rails and I'm able to run kamal deploy with success.
However, I'm having issues accessing the website in production after deployment: when I access the website URL www.theaddress.com (or the IP of the set up NodeBalancer at 139.144.161.121), I get "This site can't be reached" in the browser.
How to solve the issue? What to check?
This is the deploy.yml:
