Rsync and scp do not work when system is the remote connection

This is a pretty weird problem. I have a desktop running openSuse Tumbleweed (192.168.0.YY), and on that machine, I can send and pull files from other computers on my network without any problems. If I try to use rsync (or scp for that matter) from any other machine to push or pull files to or from this particular computer, rsync hangs after the login prompt. This is the command I'm using from the other computer(s):

> rsync -avvv 192.168.0.YY:/home/USER/test ./
opening connection using: ssh 192.168.0.YY rsync --server --sender -vvvlogDtpre.iLsfxCIvu . /home/USER/test  (8 args)
USER@192.168.0.YY's password:

It will just sit there indefinitely. If however, I'm logged into the problem computer and try to rsync with any other computer on the network as the remote, then it works without issue. I can ssh into this machine without any problems from anywhere else on the network. And journalctl indicates that the ssh logins from the other computers when I run rsync are successful, because when I interrupt the command it shows a disconnect entry for sshd:

Received disconnect from 192.168.0.XX port 57852:11: disconnected by user

I've tried scp, which has the same behavior. Has anyone else ever seen something like this? Which other logs should I check to see if I can find any error messages?
