Cant view folders on windows 8.1

Hey, all my newer windows devices access just fine and have the drives mapped in my computer. But on this older one I cant get in to map them. TS-233 and is offline (no internet access). Im on the same network and can log into the NAS just fine with 192.168… In my computer under network the NAS shows up but has no folders but it also hasnt allowe me to sign in anywhere.
Everything shows up in QFinder Pro and under connect, storage plug and connect i get the sign in option and then an error, failed to discover the iSCSI target, IP for NAS is correct and port number is entered but Ive never had to do that on any other machine.

This almost sounds like a windows issue but why can i get it just fine on win 10 and 11 but not on here?

Thanks
