I first started my DAS MNs on the 22/08/2017 using version 0.12.2.0 and they worked great until I updated to the newer version 0.12.2.1.5 the other week. That's when it all went tits up and I downgraded back to the version I was using before (0.12.2.0) and they have been working fine since.
Why do people keep saying the 12.2 version is rubbish and ban the 12.2 IPs etc? It works absolutely fine for me.
I am using the 0.12.2 wallet as a controlling Windows wallet and the same version on all of my Linux MN nodes... I haven't touched the 'new' wallet and I am receiving reward almost every day ever since...
I'm going to go back to that too when I have time - how many DAS you getting per day from each node?
I am getting about 1 Das a day as an average... Recently increased a bit, probably due to the drop of the number of masternodes.
