I've followed the instructions to set up a wikibase sandbox on my local. I used the minimal install to launch my wikibase. I have verified that all three containers are up and running. However, I get ERR_EMPTY_REPONSE when I tried to access my localhost from the browser. In the past, I have successfully deployed a wikibase sandbox with the same process before (I think it was tags/wmde.13), but I started to encounter this issue since last week. Please let me know if I need to provide more information.
