I do the same thing on another computer with IPv4 address and apparently it worked.

Thank you Dr Victor for your help!

I will explain to you exactly:

I downloaded windows wallet. I installed the wallet on my computer, i do all that i saw in this links:

And after that i restarted the wallet and it's not opening anymore. Look what the error says: https://i.imgur.com/shJ6KlG.jpg

Before i make the final step (jiyo.conf), it was nothing in masternode tab.

I have new type of IP but i don't think it's a problem.

In theory, everything is good, but it doesn't work .. help .. please?

I find these codes. But now it says "invalid port detected in masternode.conf" I used 6080 port, it's the right port.
Any ideea how to solve this? Please?

Hi guys!

In masternode.conf says that i should enter a line like this:

Format: alias IP:port masternodeprivkey collateral_output_txid collateral_output_index

From where i can take the following:

masternodeprivkey
collateral_output_txid
collateral_output_index

Thank you!
