I'm new to this and trying to learn how things work. Now, I'm trying to mine test litecoin using minerd. I've been trying to follow these instructions. The miner seems to find some test coins, but no reward appears. I'm probably making some simple newbie mistake, but I don't have any idea. I'm hoping one of you folks will be able to tell me.

I'm running on CentOS Linux 7.6. Software versions:

-bash-4.2$ litecoind -version
Litecoin Core Daemon version v0.17.1rc1
...

-bash-4.2$ litecoin-cli -version
Litecoin Core RPC client version v0.17.1rc1
...

-bash-4.2$ minerd -V      
cpuminer 2.5.0
 built on Mar  3 2019
 features: x86_64 PHE SSE2 AVX AVX2 XOP
libcurl/7.29.0 NSS/3.36 zlib/1.2.7 libidn/1.28 libssh2/1.4.3

So I start the server using testnet.

[litecoin@server ~]$ litecoind -daemon -testnet -datadir=/x/B/litecoin 
Litecoin server starting

I have an address I created earlier with litecoin-cli getnewaddress.

[litecoin@server ~]$  litecoin-cli -testnet -datadir=/x/B/litecoin getaddressesbylabel testaddress
{
  "QWZdEoxj6rfV9rt641YhTY2mzAN5xHfpwm": {
    "purpose": "receive"
  }
}
[litecoin@server ~]$ litecoin-cli -testnet -datadir=/x/B/litecoin getbalance
0.00000000
[litecoin@server ~]$ litecoin-cli -testnet -datadir=/x/B/litecoin listtransactions
[

So I run the miner and after a while it finds something.

[litecoin@server ~]$ minerd -a scrypt -o http://127.0.0.1:19332 -u user -p pass -t 2 -D  \
       --no-stratum  --coinbase-addr=QWZdEoxj6rfV9rt641YhTY2mzAN5xHfpwm

But, there's nothing there. No credit for the find.


[litecoin@server ~]$  litecoin-cli -testnet -datadir=/x/B/litecoin getbalance

I'm sure I'm doing some simple thing wrong, but I don't know what, and I don't even know how to look. I would appreciate a clue, since I don't have one.

Thanks.
