Getting blocked host in the logs when trying to reach the API.

[alessandrocarrese]

Hi! I installed Keygen via Docker on a Ubuntu Lightsail Machine.
I also installed Postgres and Redis.
The reverse proxy is nginx with a Certbot-generated SSL certificate. Nginx is doing proxy_pass to localhost:3000.

The setup worked fine, I used my domain (without the protocol as host).

I also started the API container with my domain as an env variable (in that case with protocol, since I am unsure if I need to use it).

When I try to access the API via ping/health I get this log:

[ActionDispatch::HostAuthorization::DefaultResponseApp] Blocked host: test.kg.{mydomain}.com

Do you have any idea?

You likely don't have the KEYGEN_HOST environment variable correctly configured.

This is not the entire stack trace. At the top of the stack trace, there is an error message that will tell you what's wrong.

From a cursory glance, it looks like your Redis instance is not started or is not responding.

I am going to check that, thanks! Unfortunately, I could only access Portainer at the moment for the logs and it removed the first lines.

Error connecting to Redis on 172.26.10.197:6379 (Errno::ECONNREFUSED)

You are right, thank you!

For other people reading that may have the same issue with Redis on the host, make sure to change
/etc/redis/redis.conf

bind 0.0.0.0 instead of bind 127.0.0.1

banal thing, but sometimes.. :)
