On-premises data gateway not showing on only one semantic model

[ImPalaBI]

I have several reports in a EC2 Windows server. In that same server, I have SQL database.
So I create my Power Bi reports accessing that database via localhost connection.
I have a personal data gateway installed on this server, so when I publish my reports, in the semantic models I choose that gateway and can schedule refreshes for all my data.

This have been working for years, but for this new report (that I made starting from other report, just adding more tables) the gateway is not listed, and I´m unable to refresh the data. Can someone point why this is happening and how can I fix it? I heed to create new reports, and I’m afraid this could keep happening.

This is the gateway options inthe semantic model that is failing:

This are the working settings in other semantics models of the same source:

make sure the spelling is the same throughout with no extra spaces etc.

Note: Your setup is quite a bit aways from the recommendations.

- Use FQDNs for connection sources

- Don't put a gateway on the same machine as a database

- don't use personal gateways 

- have more than one gateway cluster member

Where? I just checked all the contents in the advandec editor, no spelling errors. Is there any other place I should look for?

Thanks for the advice.
