I swapped out the last 3 digits of the above URL with XXX.
Also, network connection is confirmed to be working.
I had encountered this same issue before, and thinking I had done something wrong and It was a one-off issue, I re-installed the OS and Mycodo along with setting up all the code for the lights, water, humidification, fans, etc. This took quite a lot of time.
Is there a way to find the source of the issue and correct it?
Are you sure that the IP address hasn’t changed for some reason? Can you still ping or SSH into the Pi with that IP address?
Did you run
Sudo apt update
Sudo apt upgrade
before installing Mycodo? (The Mycodo install script should do this anyway, but not a bad idea to do it manually before installing anything.)
It sounds like the install did not complete properly, maybe the web server isn’t running?
Did your install log show any errors?
A ping is the only real relevant thing here. If you cannot ping the device, then the IP address has likely changed. You should always ensure to set up a static IP address in your router or the Pi’s config otherwise you should expect it to change at some point.
