502 Bad Gateway Error

1

New install of Anthias works fine.

I try to enable basic_auth in .scrrenly/screenly.conf

I’ve tried both:
auth_backend = -and-
auth_backend = auth_basic

with
[auth_basic]
user=bob
password=sally

Then running:
screenly/bin/upgrade_containers.sh
and rebooting.

Going back to the original IP address results in the 502 error.

Messages look like:

@Dhe, I would like to request for the following logs:

  • server logs
    cd ~/screenly
docker compose logs -ft anthias-server
  • viewer logs
    cd ~/screenly
docker compose logs -ft anthias-viewer
  • nginx logs
    cd ~/screenly
docker compose exec -it anthias-nginx
tail -f /var/log/nginx/error.log # You can also check `/var/log/nginx/access.log` as well.
3

root@myhost:/home/root/screenly# docker compose exec -it anthias-nginx
requires at least 2 arg(s), only received 1

4

@Dhe, my bad. It should be:

docker compose exec -it anthias-nginx bash

@Dhe, thanks for providing the logs. I’ll further look closer on the issue. It looks like an encoding issue that needs to be fixed. I’ll keep you posted on the fixes.

You can also create a pull request if you’d like. Contributions are always welcome.

@Dhe, it looks like you’re trying to store the password (in your case it’s “sally”) as it is.
You have to put a hashed version of your password in ~/.screenly/screenly.conf.

You can use this online tool to get the hashed version of the password. If your password is sally, then you should put 97897a111d485af1048bece173d2980a15870ca079281b79c7ca755356847602 instead.

I’ll update the documentation for setting the password via ~/.screenly/screenly.conf.

@Dhe, I just created a pull request to modify the documentation for HTTP basic auth. Take note that you can also change your login and password via the web UI (in the Settings page).
