I already installed Umbrel on my Raspberry but when I started it and tried to go to the Umbrel site: http://umbrel.local or http://umbrel it gives me the following message: Wow… This page cannot be accessed
Try to access again. And if you cannot access try to reflash the SD card
Instead of accessing Umbrel using umbrel.local, try to access it using your Raspberry Pi’s local IP address. You can find the IP address by running: hostname -I
Then open http://<your_pi_ip_address> in your browser.
