I forked DASH a week ago. I am able to generate genesis block hash, merkle hash. I created one VM (ubuntu 16.04) for rpc server. Another one VM For mining. I am able to establish connetion between two VMS's. But when I want to mine genesis block. I cant able to do so and I get the following error.

Launching miner...

[2018-08-09 12:03:38] json_rpc_call failed, retry after 30 seconds

I am currently trying to mine using ("minerd") provided by dash. Could anyone please help on how to solo mine using minerd or anyother app.

The mining software (darcoin-cpu-miner- in dashpay github). It used getwork method. I changed to cpuminer which uses getblocktemplate and supports x11 also. After that I run my altcoin mining. Then it started working.


Unless you won't implement a stratum on your server to connect in a "pool fashion" to your daemon you should use getwork or direct connection methods to mine.
