spite

I had that plug-in installed and it never skipped a single intro for me

Dunno, maybe it was storage. I had a SATA to USB3 drive hooked up to it. Couldn’t have been network. I got some old office PC with i3-6100 for free, hooked it up to the same cable, same router port and everything is working mostly smooth now, on similar drive but connected directly to SATA

Yep, 4k, sometimes with HDR. It was happening mostly on those. But 1080p files were also sometimes affected

I’ve recently set up pivpn with duckdns. Are there any security related steps I should take or is the out of the box config good enough?

It doesn’t. Not well. And for larger files, even on cable connection without transcoding performance is god awful, sometimes it doesn’t play, or stutters or you get awful audio desyncs. Don’t do jellyfin on rpi
