Hello EnergyVampire,

you need to be able to access the ecoinpool mining port you specified from your browser. The link in that error message should directly take you there (click it!), presenting you a greeting message. If your browser cannot connect to ecoinpool in this way, you either have too restrictive firewall settings (if not running on localhost only) or ecoinpool crashed because of bad configuration or it's unable to connect to bitcoind or bitcoind is still loading the blockchain or ecoinpool is unable to connect to CouchDB and other reasons which are fatal for ecoinpool.

If you get an error message, try to paste it on pastebin.com after you read this guide and send the link as a pm here or contact me on IRC. Maybe I can help you then.
