Re: trestclient Connection refused: connect

Hi 
For Discogs development, please read Discogs API document. To me, you don't use the right URL for a rest web service.

Re: trestclient Connection refused: connect

IMO problem with SSL certificate from server you want to connect:

either it is not valid by host verification (certificate issued for host different where it used);
or (most probably) java do not trust it as knows nothing about it - and this can be solved by importing server certificate into java trust storage.
