How to set up solo Yacoin mining on Linux

[djm34]

Hello,

I want to do solo mining of Yacoin on Linux, however I doesn't seem to work.
I have install the yacoin package, updated the chain block.
Created a yacoin.conf file (actually the one I use windows).

But then when I try to start my miner, I just get connection refused (or error 500).
Is there something I could have overlooked ?

Thanks for your help
