Basic installer script not working, leaves a fresh node unreachable on port 80/443

[timjrobinson]

❗️ Fresh script install leaves node unreachable on port 80/443

Item	Value
Script URL / commit	installer.dappnode.io (fetched 2025-06-03)
Host OS	Ubuntu 24.04.2
Chosen LAN domain	dappnode.local
Broken core pkg	DAppNodeCore-https.dnp.dappnode.eth 0.1.3
Working backend	dappmanager.dnp.dappnode.eth 0.2.99 (listens on :80 in-container)

What happens

1. Run the script on a clean box → installer finishes.
2. All core containers show Up, but any of
   http://my.dappnode · http://dappnode.local · http://<IP> · https://<…>
   fails with the symptoms below.

Client symptom	Container log
curl: (52) Empty reply or SSL_ERROR_SYSCALL	https log: undefined local variable or method 'dappnode_domain_once' for NAConfig:Module
508 Loop Detected	Traefik (query by IP)
403 Forbidden	Nginx default v-host (query by IP)
502 Bad Gateway	Any DIY proxy pointing at dappmanager:8080

Root cause

• DNP_HTTPS 0.1.x crashes during entry-point → Nginx never binds 80/443 → kernel RSTs every inbound connection.
• Even if you patch the crash, the proxy template still points at :8080 while current dappmanager actually listens on :80.

---

Quick work-around

# 0. Ensure LAN DNS resolves dappnode.local ➜ <node ip>

# 1. Remove the crashing HTTPS package
docker rm -f DAppNodeCore-https.dnp.dappnode.eth

# 2. Drop in a tiny reverse proxy on port 80
sudo mkdir -p /opt/dappnode-proxy

sudo tee /opt/dappnode-proxy/dappnode.conf >/dev/null <<'EOF'
server {
  listen 80 default_server;
  server_name dappnode.local;
  location / {
    proxy_pass http://dappmanager.dnp.dappnode.eth:80;
    proxy_set_header Host $host;
  }
}
EOF

docker run -d --name dappnode-proxy \
  --restart unless-stopped \
  --network dncore_network \
  --network-alias dappmanager.dnp.dappnode.eth \
  -p 80:80 \
  -v /opt/dappnode-proxy/dappnode.conf:/etc/nginx/conf.d/dappnode.conf:ro \
  nginx:alpine

After that, http://dappnode.local loads the installer/dashboard fine.

Other possible fix?

Looks like after I got this running, I got a notification that there is a new version of the https package. When trying to fix the issue before I wasn't able to download this for some reason. So the script needs to be updated to use the new package.

It looks like the https package has been updated in the code but maybe the installer hasn't been republished since it was updated?

[timjrobinson]

I updated the https docker container to the latest and tried running it instead of my simple proxy and it still doesn't work. I also tried changing the hostname to my.dappnode instead and that didn't work either. Are the installer scripts just super out of date?

[3alpha]

Do you have something preinstalled on OS that binds to port 80/443? Looking at your workaround it seems like it might be NGINX which causes DNP_HTTPS to crash.

Try disabling/uninstalling that and see if DNP_HTTPS still crashes.

[timjrobinson]

No there wasn't anything running on those ports. I created a basic nginx proxy after the http server never worked.

Why is it version 0.1.3 instead of 0.2.2 and why is it dappnode.local instead of my.dappnode? That seems to be the root of the issue, that the installer scripts are out of date or haven't been kept in sync with the iso image.

[timjrobinson]

I tried installing from an ISO image and also having the same issue. Is dappnode just broken ATM? Seems like no installation method works properly. The http server is 0.1.3 again with the latest ISO instead of 0.2.2.

All I did was Unattended install, then on other machine set ip dappnode.local in my hosts file, then when I visit http://dappnode.local from another PC it just gives 502 Bad Gateway, same as it did with the script installer.

The fix mentioned in my original post replacing the current proxy with a simple nginx server works correctly
