I have installed OMPD through the DietPi “software optimised for your system” menu.
According to OMPD docs, OMPD should then be accessible at http://(ip address of DietPi device)/OMPD.
I have tried this, I have also tried http://(ip address of DietPi device):port/OMPD and http://(ip address of DietPi device):port.
I get “refused to connect” on everything except what the instructions say, http://(ip address of DietPi device)/OMPD, where the error is instead 404 Not Found.
Can anyone help with this please ? Thank you.
