I had to re-install my Hyperion NG on my Raspberry Pi which is dedicated to running the LEDs - SD card had died
The service hyperion@pi.service does not start upon new install with version 2.0.15
Hence no access to web page upon first install
I have to ssh in and start and enable the service .... after that all is good
sudo systemctl start hyperion@pi.service
sudo systemctl enable hyperion@pi.service
sudo systemctl status hyperion@pi.service
I used the Raspberry Pi imager to install Hyperion to the SD card and enable ssh
