I want to code a plugin for my specific needs and started doing the "Plugin Tutorial" (Plugin Tutorial — OctoPrint master documentation). For that I've set up an Ubuntu vm with a dedicated account for plugin development. There I installed the OctoPrint venv. Things went relatively smooth until the frontend section (Plugin Tutorial — OctoPrint master documentation). I simply do not know how I connect to the web UI (like with a normal RPi, octopi.local or IP) after I start the virtual octoprint server with "octoprint serve".
