You can share your .bat file here and a screenshot of the error, how many cards do you have?

Here is my bat for the computer with the wallet and 750ti's (total of 5):   skminer.exe 127.0.0.1 9325 5 20

On the image I don't have an account anywhere to upload and not sure how to insert but it says

Initializing Miner 127.0.0.1:9325 Threads = 5 Timeout = 20
connected to 127.0.0.1:9325...
[Master] Failed to Update Height
Connected to 127.0.01:9325...
[Master] Failed to Update Height
Repeats this until I terminate the miner

The computer with the 970 shows the same thing except for the 127.0.0.1 it has the ip address of the computer with the wallet running.

I have a config file to solo from another computer and it is:
rpcuser=MYUSER
rpcpassword=MYPASS
rpcallowip=127.0.0.*
rpcport=9325
server=1
daemon=1
listen=1

The wallet was created with a short cut and I went into properties and added the -server.

This is always how I have solo mined and haven't had any issues.
