Hint for Sunday

Not sure if this is the right direction, but I’m trying a basic brute force for a service on the host and 2 well known tools are completely shitting themselves and not working at all. Don’t want to give too much away, so if someone wouldn’t mind dropping me a DM and giving me a second opinion, I’d really appreciate it.

EDIT: Neeeevermind. Used a different tool and had success. Still not sure why the other two didn’t work, but whatever!
