I just did a random check on my docker pihole container and found the webportal wasn't responding. It appears the DNS is responding but can't tell for sure without crashing my whole network(I have a fail over DNS setup in DHCP. Response time appear as if it is working). I went digging and the common problem is lighttpd so I checked into the console for pihole and I am getting repeating
pihole | Stopping lighttpd
pihole | lighttpd: no process found
I see no error as to why lightttpd isn't starting or why it trying to stop. I thought I may have a permission issue. So I tried setting user permissions in the compose file to 1000:1000. Tried setting PI-HOLE user variable and WEB User variable. Tried outputting the lighttpd log to a host volume. All of this resulted in permission denied issues.
It was running normally before so I am not sure what has changed to cause this error.
