Due to application versions, I have 3 laravel Homestead boxes. I'm using MacOS.
For each of them I do:
v10.17
laravel/homestead 9.7.2
Welcome to Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-124-generic x86_64)
$ vagrant ssh
then
$ mailhog

Why isn't mailhog working in my latest Laravel Homestead?
Final notes: In my case, Mailhog does work in laravel/homestead box v11.3.0, but not on v11.4.0 , why?
In recent releases of Laravel Homestead, the server IP address has changed. For example, in latest Laravel Homestead, the IP address is 192.168.56.56. So in order to access to mailhog in the browser, I must type the given IP address, followed by the Mailhog port like so:
http://192.168.56.56:8025/
and that did the trick.
