Please tell me how to solve this problem.Thank you .
Are you creating a new masternode or bring up an existing one?
Seems that you are using a used collateral
bring up an existing one.
I’ve changed the collateral address, but it’s still like this.
use the protx update_service command
But my problem hasn’t yet been solved.
If you are using Electrum Firo with a hardware wallet, please use protx-related commands with the Firo Masternode Tool instead.
