Metabase seems to be running but I can't connect

Hi all,

I am on a fresh Debian install:

# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)
Release:        10
Codename:       buster

I installed Java as per:

# java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9 (build 11.0.11+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+9 (build 11.0.11+9, mixed mode)

If I run metabase I get the following output:

# java -jar metabase.jar
WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.
2021-08-26 19:56:59,831 INFO metabase.util :: Maximum memory available to JVM: 988.0 MB
2021-08-26 19:57:11,251 INFO util.encryption :: Saved credentials encryption is DISABLED for this Metabase instance. 
 For more information, see

There seems to be no response from the server:

# curl http://localhost:3000/api/health
curl: (7) Failed to connect to localhost port 3000: Connection refused

Also nothing listening on port 3000

# netstat -nupta | grep 3000

I followed the steps here to set it up and have Postgres and Nginx installed, but there is no difference when running as a service:

# cat /etc/default/metabase

# systemctl stop metabase
# systemctl start metabase
# systemctl status metabase
● metabase.service - Metabase server

I can login to postgres with the following command (and password):

# psql metabase -U metabase -W -h
psql (13.4 (Debian 13.4-1.pgdg100+1))

Type "help" for help.


Any suggestions how I can make this work?

Hi @rvavruch
My first guess is that you are running out of entropy:

Thank you. I followed the instructions here: and it is now working.
