I got myself a masternode 5 weeks ago feeling happy about the investmeent and the opportunity to pay back to the community. First two weeks all went fine, but in the last three weeks my masternode have gone inactive four times, without getting any rewards. I use the vultre service. i have followed TAO's guide both when installing and updating to 0.12.2. Does anyone have any advice for me to get the masternode working properly, or should I just sell my 1000 DASH and invest it elsewhere?
