Jellyfin failing to start due to Kestrel failing to start

[csaavedra]

I have Jellyfin 10.10.6 in a bare Nano Pi with Armbian, I only use it in the LAN. Yesterday the OOM killer killed jellyfin due to high memory usage, and after that it has refused to start with the logs showing that Kestrel fails to start. Nothing has changed in my configuration, so I have no idea what's going on here.

First, here are excerpts from jellyfin starting and failing:

Here are the contents of my network.xml:
