Hey, for some reason when I run the docker-compose tao-ce file everything spawns without errors, I have also done the etc/hosts change like in the instructions, I still can’t get my browser to route to any of the containers with the 0.0.0.0 or community.tao.internal. I have tried with or without HTTPS.

I am using Firefox as browser and the error I get: "Unable to connect

Firefox can’t establish a connection to the server at community.tao.internal.

- The site could be temporarily unavailable or too busy. Try again in a few moments.

- If you are unable to load any pages, check your computer’s network connection.

- If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I also checked that my OS is listening to port 443 via docker proxy.

I am using Ubuntu 24.04.4 LTS

Any help is appreciated!

Hello ! thanks for contacting us!

Firefox may be trying to resolve `community.tao.internal` with [DoH](https://en.wikipedia.org/wiki/DNS_over_HTTPS) (which completly ignore `/etc/hosts` file); you may have to add this domain in DoH exception.

To do so, open Firefox Preferences, search for `DNS`, and click on `Manage Exceptions...` in `DNS over HTTPS`.

Then add `community.tao.internal` in the list.

Let us know if it helps!

Hey, actually the problem was the 0.0.0.0 in etc/hosts like it’s told in the documentation. Changing the IP to 127.0.0.1 solved the issue.
