Hey PiGuy, the Check page at https://galaxy.qtum.org/check may not be validating new registrations because we are between Qtum Galaxy programs right now.
But there are some thing you can check:
Running the latest version 0.18.3 of the Qtum Core wallet. If not, run the update.
getnetworkinfocommand and look for
“subversion”; “/Satoshi: 0.18.3(Q_your_prize_address)/”,
getpeerinfocommand and look for
At the top of that list.
If your wallet meets these conditions it will register when the Full Nodes Program resumes, which is soon.
