Error when using title id finder, help please

my horizon starts normally but when i try to use the title id finder tool it flashes a error screen but nothing like one i’ve seen in tutorials trying to fix this issue, here’s the image


it’s in portuguese but it says: “unhandled exception…”, and at the bottom “the underlying connection was closed: unexpected error in a send” or something along those lines. if somebody can help i appreciate

Horizon’s “title id finder” feature is not working at all, sorry.
