Getting - n8n Error Get "https://docker.n8n.io/v2/": dial tcp 0.0.0.0:443: connect: connection refused

Describe the problem/error/question

When trying to run docker compose up -d, after creating the yaml file, I get hit with - n8n Error Get “https://docker.n8n.io/v2/”: dial tcp 0.0.0.0:443: connect: connection refused

I can ping out to multiple IPs, but this is the last step I am getting stuck on. I’m also a noob when it comes this stuff so I am learning. Look forward and can provide more details as needed.

What is the error message (if any)?

n8n Error Get “https://docker.n8n.io/v2/”: dial tcp 0.0.0.0:443: connect: connection refused

Hello @bigdave2oo4 hope all is well, welcome to the community.

It appears that for some reason docker.n8n.io resolved to 0.0.0.0 for you, which shouldn’t be happening. Are you doing this from a work environment or from home? It is often that companies use dns resolution to block access to certain resource and resolving certain domains to 0.0.0.0 is one way to do it.

Hello,

I’m trying to install this on my Proxmox homelab. Oh a Debian LXC with 2vCPUs, 8GB of memory, and 100GB of storage. Assigned it an IP during setup. I setup the domain on my PiHole and replicated it out to my other others ones. I do have a DNS resolver that I did with my PiHole setup. Any guidance would be great, this is my last step before I can dive deep into n8n.

Which ever dns server resolves queries about that domain (docker.n8n.io) needs to stop resolving it to 0.0.0.0 as this is a way to blackhole the requests. It needs to resolve it to its actual IP.

Okay, so it apparently didn’t like my DNS IPs. Maybe because of my lists or etc? Idk, buy I switched the DNS IPs to Cloud flare and Quad 9 and it’s pulling the images. Thank you for the step in the right direction!
