Could you post your full logs as that snippet is not helpful. See the red section above.

Sorry for the delay. I had started looking at it then something else came up and I had forgotten this.

Usually when no files show it is due to a database error but I don't see this in the logs.
I do see what it triggering the error, it is a browse request from the renderer just before each instance.

Code: Select all

Received a request from 192.168.1.27:
============================= UPNP HTTP SERVER REQUEST BEGIN ================================

============================= UPNP HTTP SERVER REQUEST END ==================================
I don't know much about these requests but it looks correct.
Comparing it to my PS4 I thought the problem was with the <Filter> or <SortCriteria> fields as they are different but I found some UPnP dev tools to send the same request on my computer and it works just fine.

I suspect it could still be a database issue, just one that is not showing an error. I did see this message that might be related.

Code: Select all

Node (net.pms.store.container.MediaLibrary) already has an ID (100), which is overridden now. The previous parent node was: MediaStore[[]]


Try renaming or deleting your database at C:\ProgramData\UMS\database while UMS is not running and a new one will be built when it is next run.
