I have a small home HEOS setup (2 Amps and 1 Link) pulling music from a Synology DS223 NAS with about 10,000 artists and 100,000+ tracks. Everything worked perfectly until I switched ISPs from Comcast to fiber optic, which changed my home network.

Since the network change, HEOS only shows roughly 1,000 artists instead of the full library. Audio Station on the NAS displays all 10,000+ artists correctly, so the files and metadata are fine.

What I've tried:

Factory reset all three HEOS devices multiple times
Re-added network shares using every path variation (IP-based, hostname-based)
Changed Synology Media Server display format settings
Toggled NTLMv1 authentication on/off
Run full re-indexes repeatedly
Verified file permissions and folder structures

Observations:

Example: The Beatles only appear with one song (a Pat Benatar cover where they're listed as a contributing artist), but none of their own albums show up
Artists seem randomly incomplete - no obvious pattern by letter, date added, or genre
HEOS does see the NAS and connects successfully - it's just not indexing the complete library

My questions:

Is there a known library size limit for HEOS indexing over SMB/network shares? That seems weird since this isn't that big of a library and it worked with Comcast.
Would switching to Plex Media Server actually help, or does HEOS have similar limitations when accessing via DLNA?
Is Roon a better solution obverall + HEOS integration?

I've spent days on this and I'm at a loss. The hardware sounds great - I just can't access most of my music anymore.

Any insights would be hugely appreciated.

Which DLNA do you like best? Why?

HEOS showing ~1,000 artists instead of 10,000+ after network change - what am I missing?
