Jetty error on shared links

[wezman2k]

Hey guys, hoping I can get a little help with this.

I just migrated from an Airport Extreme (latest gen) to an Asus RT-AC68R. Ever since, shared links in subsonic don't work properly. I can access my server using the subsonic.com url just fine so I know port forwarding is behaving the way it should.

HTTP ERROR: 404

/WEB-INF/jsp/externalPlayer.jsp
RequestURI=/WEB-INF/jsp/externalPlayer.jsp

Any feedback is appreciated, thank you!
