I left my media server unattended for 14 days, and the strangest thing broke first

I can't deny having just a tiny bit of anxiety every time I travel and leave my home server unattended. For months now, my Jellyfin server has been quietly doing its job, but not without the occasional TLC and upkeep from my end. As such, when I left home for a couple of weeks, I knew I'd have to keep it running, especially since my Jellyfin serves movies and TV shows to my friends as well. If something was going to fail, though, I'd assumed it would be something inside the server, like a drive, Jellyfin itself, or some other piece of software. A home server has plenty of moving parts, so it's only natural to expect one of them to be flaky. Plus, two weeks is enough time for something to go wrong when nobody is around to fix it. What I definitely didn't expect was for the server to keep running perfectly while something else entirely brought the entire setup to a halt — something bafflingly mundane. Plenty can go wrong with an unattended home server The server still wasn't the part I was worried about Leaving a home server unattended for two weeks sounds like a decent way to discover which part of it you've been foolishly trusting. My Jellyfin setup has plenty of potential failure points, from the 2TB hard drive holding my media to the operating system and the various services running alongside it. Theoretically speaking, any one of these failure points could decide to misbehave while I was several hundred miles away. The hard drive was the obvious candidate, since drives fail and there isn't much you can do about it (aside from keeping backups). Jellyfin itself was another possibility, since an update could introduce a bug, a database could become unhappy, or a service could just stop running after a restart if a power outage lasted long enough to outlast the UPS's battery backup. Configuring your server to listen to UPS signals via software like NUT or apcupsd can prevent abrupt shutdowns if the battery runs low. The less dramatic problems can be just as bad — storage can disappear surprisingly quickly when logs, temporary files, downloads, thumbnails, and backups are all sharing the same machine, and any one of them could stop working out of the blue. This setup had already been running reliably, and I wasn't expecting two weeks of unattended operation to suddenly expose some catastrophic flaw in my system that would have me rewiring. If something did break, I assumed it would be something obvious, local, and relatively easy to blame. I was wrong on all three counts. It was the network that broke the server's back The server was fine, but the network wasn't A few days into the trip, my friends suddenly couldn't access my Jellyfin library, which resulted in me waking up to a very angry group chat. But when I looked at the camera feeds back home, everything seemed in order. The machine was still running, and I saw no flashing red lights anywhere. Even my Jellyfin server at home was working well on the local network, so clearly, my server itself hadn't decided to take an unscheduled vacation either. It was clear that everyone outside my home had lost access while the machine itself appeared perfectly healthy. The problem was somewhere between the server and the internet, and I only got to the root of the issue a full week later after getting back home. I had to point the port-forwarding rule at a new internal IP. Turns out, my ISP had pushed a major firmware update to the router while I was away. Previous updates had always preserved my settings, so I had no reason to expect this one to behave differently. However, this time, the update had reset my port-forwarding configuration, meaning the rule that allowed outside connections to reach my Jellyfin server was simply vaporized. Putting things back the way they were wasn't as easy as simply re-adding the port forward. The update to my router (and the consequent hard restart) had apparently reset my DHCP reservations as well. As such, I had to point the port-forwarding rule at a new internal IP, which, while not any trouble at all, felt worth mentioning. With that, everything immediately worked again. Neither my drives had failed, nor had Jellyfin corrupted my database. A simple five-minute affair — the firmware update — had changed one configuration, consequently making my entire media library inaccessible to everyone who wasn't sitting in my house. My server wasn't the weakest link Self-hosting doesn't mean controlling everything Clearly, router firmware updates can be annoying. I've come to realize just how many things have to go right before someone can actually watch a movie from my server. Even when Jellyfin and my storage are perfectly healthy, the connection leading to it all can throw a massive wrench in the works. This also turned out to be a rather easy dependency to overlook, especially since the router is one of the few components in the home network that usually "just works." Once port-forwarding is configured, there isn't much reason to think about it again. But that configuration is effectively part of the server's infrastructure, even though it lives on a completely different device and is controlled by the ISP. When it disappeared, my supposedly self-hosted service went with it. What I've learned from this unintentional mishap is that uptime isn't simply about keeping the machine powered on. Backups and drive health still matter, but there's a different way to think about server reliability. The boring components and failure points deserve some attention, too. I had spent most of my attention making the thing running Jellyfin reliable, while the thing connecting Jellyfin to everyone else was allowed to quietly become a single point of failure. Jellyfin iOS compatible Yes Android compatible Yes Desktop compatible Yes Jellyfin is one of the best Plex alternatives you can get, and that's thanks to its open-source nature and powerful set of features. There are apps for basically every platform and it's completely free to run your very own server. The boring stuff deserves attention too In an odd way, it's been reassuring that my home server isn't as fragile as I thought. It means the next time I leave town, I won't be imagining every hard drive clicking itself into oblivion or Jellyfin spontaneously deciding to ruin my week. Instead, I'll probably spend a little more time thinking about the surrounding infrastructure, which previously hasn't warranted a lot of attention on my part. Reliability really isn't a single switch to turn on after configuring the server. It is the accumulated result of dozens of small things continuing to behave exactly as expected. Most of them will, most of the time. The challenge, then, lies in figuring out which seemingly insignificant one can bring everything else to a stop.
