I am not able to access the GUI for LFS267 course. Machine is up but when accessing gui it gives below error-

The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

    Is port 5000 blocked or already in use on your machine?

    Also, what is your OS? What VirtualBox and vagrant version are you using?

    I was able to access the day before. I am running in Macos.

    vagrant version
    Installed Version: 2.2.19
    Latest Version: 2.2.19

    You're running an up-to-date version of Vagrant!

    VirtualBox version 6.1

    Current machine states:

    default running (virtualbox)

    The VM is running. To stop this VM, you can run vagrant halt to
    shut it down forcefully, or you can run vagrant suspend to simply
    suspend the virtual machine. In either case, to restart it again,
    simply run vagrant up.

    And you are still unable to access the UI?

    http://localhost:5000

    Given that you would access it before, it is most likely issue with the state of this vm. You can always destroy it and recreate it.

    Once issue we have seen on MacOS Monterey, a new process is using port 5000 and it interferes with vagrant port.

    You can disable that based on above instructions.

    it worked. For anyone , who might come to this scenario . i took backup of box and vagrant file. Destroyed existing box and vagrant file. And added back the box and vagrant backup then started the machine. Below link might be useful-

    But it starts from beginning(scratch)!
