### Error messages

#### Installation

**Docker**

🙋‍♂️I can’t connect to Postgres DB inside another docker container. I'm trying to install Forest Admin using docker but my database is running inside a different container and I'm using a custom port. I can access it without any problems via `psql` but then I get an error.

✅ Such an issue has been solved on our community forum. [Check it out.](https://community.forestadmin.com/t/cant-connect-to-postgres-db-inside-another-docker-container/725)

🙋🏾‍♂️ After installing Forest Admin with Docker, I expect to see my visual data. Instead, I'm getting such error:

🙋‍♂️ When I try to deploy lumber-admin via Docker with a remote database, I am getting an error `Error: Unprocessable Entity`

I suspect a problem on DB, but I cannot find any details or logs about this event. So, my main question is: where I can find any logs?

🙋🏾 I was able to link my data to Forest admin (with docker, on port 5433). When I run <http://localhost:3310> it says my app is running but when I want to log to Forest Admin on <http://app.forestadmin.com/> I first have to log in and it then says *Your server encountered an error*.

**Ruby on Rails**

🙋🏻‍♀️ I created a new project using Ruby on Rails as the datasource. I followed instructions, added gem, migrated, `dev:cache`, and started the server. Everything went smoothly, but once on the admin panel, I am getting the following message:

*Unable to authenticate you*

*Please verify that your admin backend is correctly configured and running.*
