get an error when setting up in web browser

[ralyodio]

I setup nginx with a proxy to localhost:8080 and the install page loads fine, but when I hit the submit button I get a 500. Nothing valuable in the nginx error logs.

Did you fill in localhost in de field for the database server?
I had the same error and fixed it with filling in 127.0.0.1.
