Internal Server Error- Fresh Install

Installation
1

Hi all,

Posting here to document my attempts to resolve this issue, hopefully it can help other users with a similar issue. Thanks to mods who have helped me get this far.

I have a fresh install of HA that I cannot access through the browser by any method. It is listed as a wired (LAN) connection in my router UI and responds to pings, but that is all. I have tried:

  • 15-20 re-flashes
  • several re-downloads of 32bit and 64 bit images
  • several power supplies
  • several SD cards
  • several SD card readers
  • wifi and LAN install attempts
  • specifically allowing TCP traffic to port 8123 as per this guide
  • disabling windows firewall altogether

Debugging using this guide yielded the following report:

Would appreciate some pointers from more experienced folks. I’ve had HA working in the past and it seemed great, but I’m not sure I want to automate my whole life on something that breaks on a fresh install…

This appears to be a DNS lookup issue?

It appears that it can’t resolve the URL required to download hassio images.

Thanks FM, I appreciate you taking the time.

It seems to be DNS problem associated with docker. This article suggests that these kind of errors are somewhat commonplace.

Am I able to run the kinds of tests they suggest for docker inside Hassos? This is my first foray into anything command-line related so please excuse the dumb questions. I don’t need the problems solved for me, just the right direction

4

You should be able to, since HassOS is just running Docker, the commands to test appear to be Docker only

5

Unless I am doing something wrong, I don’t seem to be able use the commands they suggest

hassio > $ docker run busybox ping -c 1 192.203.230.10
Error: unknown command "$" for "hassio"
Run 'hassio --help' for usage.
FATA[0000] Error while executing rootCmd: unknown command "$" for "hassio"

hassio > login
# $ docker run busybox ping -c 1 192.203.230.10
/bin/ash: $: not found

Pinging any ip address from within hassos is unsuccessful

hassio > login
# ping 8.8.8.8
No response from 8.8.8.8

Though I’m not sure that really tells me much more than I already knew
Is there a standard method for troubleshooting DNS errors using hassos?

6

$ isn’t a command. That indicates you are at a prompt.

7

If you can’t ping an IP address, it has nothing to do with DNS. Pinging an IP doesn’t involve DNS at all.

8

Thanks for that. I’ve been successfully trying a few docker diagnostic commands. Again not sure what they tell me yet

docker run busybox ping 192.203.230.10
Unable to find image 'busybox:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on 192.168.1.1:53: read udp 192.168.1.103:54976->192.168.1.1:53: i/o timeout.


# nslookup index.docker.io

They are telling you the network is broken. Your device has no access to the outside world. It can’t ping an IP outside of it’s network (can you ping your router?), and it will never resolve any hostnames/DNS if you don’t fix the networking.

Thanks for your reply and sorry about the delay. I ended up giving up temporarily and had to re-image to try again.

After a reinstall I can successfully ping the router and an external IP (8.8.8.8) from inside the pi. All other devices on the network can connect to the internet just fine.

Checking the supervisor logs, I am getting very different reports:

I’m pretty stumped- Same image file, same machine, same SD card and same router, same settings. However, I still can’t access the frontend.

Resetting the pi changed the supervisor output. Still can’t access the UI

Also, why would the ip address of Homeassistant be 172.30.32.1 when the pi is listed as 192.168.1.102 in my router

hassio > homeassistant info

Gday,

Did you have any luck? Im in the same boat but my DNS does work! Any help appreciated

I’m facing similar issue… After starting HomeAutomation server…after few minutes, Internet become inaccessible.

From unix, i ran following commands:

docker stats

This will give me all containers currently running. Then restart the hassio_dsn container using following command.

docker restart <containe_rid>

Internet gets restored. But again after few minutes, internet again becomes inaccessible.

Would really appreciate if anyone can suggest some permanent solution.(I’m new to HA).
