PixStar Photo frame doesn't find Serviio

Newbie alert!

I have, for some years, been using minidlna to serve photos (jpegs) to my PixStar photo frames.

I decided to have a play with serviio, but find that the photo frames simply do not offer the serviio server as a potential source of photos.

I have played with a couple of different profiles, but with no success - in any case, I'm not sure whether this is a profile problem.

Other devices (eg. Sony TV) do see the serviio server, and will display the photos.

The obvious difference is that the TV is on a wired connection while the photo frames are wi-fi only.

I do note that the Pixstar devices do not appear in the public listings of dlna-compliant devices, but they do work with minidlna.

Serviio is running in a docker container (as is minidlna) on a slackware server.

I attach a debug log - the device in question is 172.22.1.230

I have done a little more exploring, and have re-run the debug log with the device profile for the photoframe set back to generic.

I have greped the logfile for interactions with the photoframe and the same for a Sony Bravia - however, there are so many dissimilarities between the two that I don't know where to begin.

Is anyone able to identify what is going wrong with the interchange with the PixStar photo frame? If not, I guess that I would need to use a packet sniffer to compare minidlna and serviio exchanges with the photoframe.

One thought crosses my mind - would there be any problem haveing two dlna services (minidlna and serviio) running as two separate dockers on the same host server?

I attach the newer syslog, together with the grep for the photoframe messages and the grep for the TV messages.

No.

What is your subnet size - your server is 172.22.0.100 whereas your device is on 172.22.1.230. The server and devices must be on the same subnet - so normally I would say this may be your issue, however it appears that all of your renderers are in the 172.22.1.0/24 range so on that basis nothing should work (or you have a have a larger subnet?) .

Be surprised if it makes a difference but perhaps try moving your server to 172.22.1.100 and see what happens.

I can assure you that I'm running a perfectly valid Class B subnet, within the address range reserved for private Class B nets - 172.22.0.0/12. If that weren't the case, I would have lots more problems than just this.

And, as I say, the photoframes work fine with minidlna running on the same server. I'm sure that there is some problem in the dlna discovery handshaking between PixStar on Serviio - I'm just not familiar enough (at all?) with the dlna protocols to pinpoint what is going on.

Yep, thought you may have been running a larger than normal (for a home network) subnet. As you say, nothing technically invalid about it, just a little unusual compared to most networks.

It may be worthwhile still checking what I suggested, if it's easily done. Admittedly, it's a long shot.
