"no route to host" error in logs for Emby on MacOS

I have been checking logs, and I have a recurring error message with a "no route to host" exception

My installation is fresh from the internet today. 

I’m using MacOS Sequoia (15.3.2) on an M4 MacMini. 

Emby:  Version 4.8.11.0,

I have defined a single library with movie content, it has a single movie in it.

This is internal network use only. 

Can you point me in the right direction to finding the root cause?

Are you using DLNA? 

As this would point to an issue with port 1900.

Hi there, please attach the complete emby server log file. Thanks.

@Happy2Play

I disabled the DLNA service as I don't run windows. 

Dashboard > Devices section > DLNA > Untick [ ] Enable DLNA Play To

Restarted Emby, now there is no error in the logs. I will monitor

@Luke

This is the top 100 lines or so. The Error then just repeats. There has been no action on the server since yesterday.

Keeping this here for documentation purposes.

Hi, you could also try turning off the automatic port mapper in server network settings.
