Issues trying to reach localhost:3001/status

[juliomarmin]

I have Insomnia 8.6.1 on Windows

I have a local application listening on port 3001, and when I try to reach it with localhost:3001/status , I get in Insomnia 'Not Found'
If I copy the cURL command and try in a shell, I get response.

I changed the listening port to 3002, and with localhost:3002/status Insomia can get a response!

When listening on 3001, Insomnia works with url [::1]/status

I can't figure out why Insomnia does not work with localhost:3001, but works with other ports.

cURL works fine.

What's going on?
