Thought this was happening to me as well. Could access router storage but not any PC. It does work though I can verify. I'm on Win10 with ASUS RT-AC68 router.
I tried first by disabling firewall to make sure that wasn't it. Checked router settings and it allowed phone access. It turned out to be file permissions. I set it up to login as GUEST and added/gave access to specific person (GUEST) in the file folders where I need access.

Works like a charm. Looks like I'll be buying.
