Running deezer-downloader with PiHole server on the network

[dejan995]

Just to add a heads up for people running PiHole on their network.
I wasted a good couple of hours trying to fix non existent youtube-dl issues and in the end it turrned out that PiHole was blocking all the requests that youtube-dl was sending.
Keep in mind that my PiHole server is configured specificly and aggresivly to block YouTube ads. If your PiHole is using the default block list I doubt you will experience any issues with youtube-dl.
I experienced this using the Docker image but you will most likely encounter the same behavior even running the standalone app since PiHole works on the network level.

The workaround I used to fix this was as follows:

1. In PiHole, under Group Managment/Groups create a specific group. (I named mine Servers)
2. In PiHole, under Group Managment/Clients find your server MAC and IP address and add it as a client (By server I mean the machine that deezer-downloader is running on. This can be the Docker Host machine or even your PC)
3. On the same screen, after the Client is added, assign it to the group created in step nr. 1.
4. Go back in Group Managment/Groups and tick the Enable/Disable option to Disable the PiHole blocking for that group.

Keep in mind by doing this you efectivly disable PiHole for that client. All DNS queries will go through for that client, not just YouTube requests. If you are running deezer-downloader on your PC you might not want to do this beacuse you will deactivate all of the protection that PiHole offers. If you are running this on a server you are go to go.

@kmille Thank you for making this amazing software. It really helped me get my music collection up to date.
