When I access the link through my browser, I can start Hopper and see the described company profile world.
Yes. I have installed the hopper and set the correct path for it. According to the documentation, I also configured the firewall access separately. However, it still does not proceed past the serialize world stage.
Is there something I might be missing? Are there any other conditions besides setting the hopper path and configuring the firewall access to enter test mode?
