Solo mining works, as someone even found first 60mi block with these versions. On your picture I can see ver. of cgminer 3.6.6, working version is 3.7.3. Also from picture I can see the port 9088, but port for CateDoge QT rpcport=5108. So you are doing it definitely wrong.
Does solo work for you?
1. You're using an outdated cgminer. Step up to 3.7.3 which apparently works. 2. Use the right ports. It will never work if you keep using that wrong port..
