I trying to run Pi Hole on docker that is installed on my Sinology NAS, but keep getting this error.

FTL failed to start due to failed to create listening socket for port 53: Address already in use

I have looked through the debug log but couldn't identify the cause.

The debug log on Docker installations is limited in scope. As you already found out, there is another process (e.g. another instance of dnsmaq or bind) running on your Synology NAS, but the debug log can't tell us which process it is. You need to check other apps/containers running on your NAS if they bind to port 53.

Sorry Everyone, it was Synology server running on port 53
