I recently purchased a archer BE230 wifi router and I was excited for the usb port because I could use some network storage but a NAS would be excessive and too expensive, but I ran into an issue; I have been able to set up the smb share with no issue but I also have a PC off network and I would want it to have acces to this storage as well but everytime I try to add a network location it just won't connect giving me the attached error, but if I use a ftp program it works like a charm, what am I doing wrong? 

blacked out is my dns address 

This is happening on windows 11
