Tried in Chromium-Browser and Firefox-ESR. I can log in but the dashboard will not load. It works on Windows machines on the same network. We are not using Pi Hole or any other firewalls or blocking software.
This worked for a long time but suddenly stopped working a few months ago.
This also works in a Debian VM, but still not in Rasbian.

Hi
Thanks for reaching out!
I’m afraid that Raspberry Pi isn't an officially supported device for Miro and there may be issues if you use Miro on it. Also, in many cases, Raspberry Pi doesn't match Miro's system requirements. However, you can try installing a Linux-like distributive and opening Miro in a supported browser (or changing a user agent in the used browser to mimic the latest Google Chrome, if the browser has similar capabilities). Sorry we cannot be of much help here!
It seems that everything works fine on Windows, so using it to open Miro would be the most straightforward solution.
Hope this works for you!
