dev.blawx is down

[piers109uk]

Hi, I've been looking to play around with Blawx, but the demo url appears to be down. When I visit https://dev.blawx.com/ I get "DNS_PROBE_FINISHED_NXDOMAIN"

I also haven't been able to build the image locally or access the app on http://localhost:8000 after running docker run --platform linux/amd64 run lexpedite/blawx (I am on an M2 machine).
Here's what I get when building from source:

Happy to provide additional info. Any suggestions on how I can play around with the app?
