Seting up Piwik

hi,
I’m setting up, first time user. I’m at “database setup”, database server.
The default value was 127.0.0.1 I’m not sure what value to use here?
(all other values I leave default.

I tried the ip addess of my sinology station, the internal IP address and the default 127.0.0.1
, I get
Error while trying to connect to the database server: SQLSTATE[28000] [1045] Access denied for user ‘Janning’@‘DiskStation’ (using password: YES)

I have a WEB address www.aanning.com…I’d have to port forward, and do not know which port to use?

Please advise on how to set up.

it must be the default value for your database login
like:
if you are using mysql make sure to connect using “root” and leave password blank for first use
its become something like this “root@diskstation”
