Can you run 2 masternodes (cold, so with linux VPS) from one windows wallet ?

Already I have one masternode, It runs fine. And today I've added a new node (different VPS server). Used the same staps (beginning of this posting). And the new node starts perfect.

But the first one now seems to be "Not in the masternode list" according to the Windows wallet. At VPS level the debug command (reliefd masternode debug) shows : "not capable masternode: Could not find suitable coins!"

In the wallet there is more than 100.000 coins so the coins are there.

What did I do wrong ?
