It seems like apparmor is blocking access to the symlink target. Qtox works with symlinks after deactivating apparmor. I guess the qtox apparmor profile needs to be corrected.
apparmor="DENIED" operation="open" profile="qtox" name="/test/.config/tox/qtox.ini" pid=1082 comm="qtox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000 apparmor="DENIED" operation="open" profile="qtox" name="/test/.config/tox/test.tox" pid=1082 comm="qtox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000 apparmor="DENIED" operation="mknod" profile="qtox" name="/test/.config/tox/test.lock" pid=1082 comm="qtox" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000
