Mining my own coin... help needed

There are some Mining guru here and I am stuck in the development of my coin, I request some help to get my coin started.

I am using ccminer to mine my own coin with Yiimp. I have setup everything and everything seems to work except that I get a lot of errors and it won't mine.

My coin is virgin, that mean it has never been mined or had any transaction. I have 4 peer connected, I have set the difficulty to 1, my coin is a fork of Bitcoin Core 0.17.0.1, RPC port is 1790, main port is 1789

Mining address was created like this:

Code:

 ./bitcoin-cli getnewaddress
39EW2oTxKPySHFHfpSr6tQTskxeTYoDqAY

Here are the errors from ccminer

Code:
