PHP error (2): fsockopen(): unable to connect to 127.0.0.1:4711 (Connection refused) in /var/www/html/admin/scripts/pi-hole/php/FTL.php:47

pman · June 4, 2023, 1:23am

Expected Behaviour:

Pi-Hole booting without Error
Sinology Nas DSM 7.0 Running In Docker

Actual Behaviour:

& Under Diagnosis I See:

	Time	Type	Message
	2023-06-03 21:20:21	DNSMASQ_CONFIG	FTL failed to start due to failed to create listening socket for port 53: Address already in use

Things to know:
I had Pi-hole running perfectly on a Rasbperry Pi uninstalled it then created this one now the error is happening. I am pretty sure I removed everything from port 53. I am somewhat of a noob so explanations or tutorials on how to help with detail are appreciated!

Please, post the compose file or docker run command used to start your container (just remember to remove the password, if set).

pman · June 4, 2023, 2:14am

Where would I find this? I am using the docker GUI on my Synology.

pman · June 4, 2023, 8:46am

is this what you are looking for?

rdwebdesign · June 4, 2023, 4:12pm

This is just part of the information.

Are you mounting volumes on your container? describe it.
What network mode are you using? bridge, host, macvlan?

pman · June 4, 2023, 4:27pm

Thanks for being patient with me!

And the network is host.

rdwebdesign · June 4, 2023, 5:31pm

On the host machine, what is the output of ss -tulnp | grep 53?

pman · June 4, 2023, 5:58pm

I used a different command because that one was not working I feel like there is a lot going on here.

Well... apparently there are a lot of things using port 53.

If you want to use host network mode you need to disable everything using port 53.

pman · June 4, 2023, 6:14pm

How would I go about disabling those. I feel like there shouldn't be anything using that port!

rdwebdesign · June 4, 2023, 6:39pm

Running the command with option -p and using sudo will allow you to identify each process using port 53:

sudo netstat -tulnp | grep ":53\s"
