Particular feed not showing

[vico93]

Hello! Thanks a lot for this tool!

I'm testing the tool to use in a bash to post in discord webhooks, but one particular feed didn't load any items:

rsstail -i 3 --format '%(title)s -> %(link)s\n' -u "https://manualdousuario.net/feed/" -n 0 -v | while read x; do echo "$x"; done

Seems to be a valid RSS feed according to W3C.
