ERR_NAME_NOT_RESOLVED

[thyeestes]

I am experiencing a strange issue with running this in a Podman container. When I use this image then I get ERR_NAME_NOT_RESOLVED error, e.g. with this site https://www.asuswrt-merlin.net/.

When I use a browserless image like ghcr.io/browserless/chrome:latest it renders just fine.

Any ideas how to solve?

Thanks

Hmm not enough information, can you show the whole docker-compose.yml ?

[thyeestes]

Sure. However I am using Podman quadlets: `[Container] #Image=ghcr.io/browserless/chrome:latest Image=docker.io/dgtlmoon/sockpuppetbrowser:latest AddCapability=SYS_ADMIN AutoUpdate=registry ContainerName=cd-browserless Network=proxy.network Environment=TZ=Europe/Amsterdam Environment=SCREEN_WIDTH=1920 Environment=SCREEN_HEIGHT=1080 Environment=SCREEN_DEPTH=24 Environment=MAX_CONCURRENT_CHROME_PROCESSES=10 Environment=ENABLE_DEBUGGER=false Environment=PREBOOT_CHROME=true Environment=CONNECTION_TIMEOUT=300000 Environment=MAX_CONCURRENT_SESSIONS=10 Pod=changedetection.pod

I'm also using a Podman quadlet with Environment=PLAYWRIGHT_DRIVER_URL=ws://sockpuppetbrowser:3000 and seeing the same Exception: net::ERR_NAME_NOT_RESOLVED

My host is Fedora CoreOS and I see the last email received from changedetection.io was August 16th, with a host reboot on the 17th.

This appears to be a Podman, netavark, and/or passt issue. I just opened the following hoping the FCOS team can reproduce the issue and possibly expedite the promotion of testing to stable : https://github.com/coreos/fedora-coreos-tracker/issues/1790

I switched to slirp4netns, because of an issue with socket activation and Traefik, so I think you can take passt out of equation.

Having the same issue. I use docker and traefik reverse proxy. It used to work just fine, did not change anything in the docker-compose but now all requests via sockpuppet fail with this error

I'm having the same issue, I'm running on NixOS with docker..

And I'm fairy certain it's something inside this container that causes the issue, if I jump into it and run

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
ping: sendto: Network unreachable

If I do the exact same thing inside changedetection it works as expected:

ping 8.8.8.8

Just a guess this image is based on alpine while changedetection is debian based, I have had dns issues with alpine based images before, any chance @dgtlmoon could try to release a version that is debian based? (or at least not alpine based) and see if that resolves the issue?

I had the same problem and I just discovered after an hour of debugging that I had the "internal" network marked as internal: true and therefore the browser container was not allowed to reach the internet 🤦‍♂️ .

Before:

  ...

  sockpuppetbrowser:
    image: dgtlmoon/sockpuppetbrowser:latest
    ...
    networks:
      - changedetection-internal

networks:
  proxy:
    external: true
  changedetection-internal:
    internal: true

After:

  ...

  sockpuppetbrowser:
    image: dgtlmoon/sockpuppetbrowser:latest
    ...
    networks:
      - changedetection-internal

networks:
  proxy:
    external: true
  changedetection-internal:
