New media has stopped matching

I've been running Plex on a DS920+ for about 4 years now. Any media that I have added in the last three days will not match. This goes for Movies and Television shows. The Fix Match option is worthless, and even adding the IMDb ID number does nothing. I'm on the most recent version (1.43.3.10896-720010896). Based on that, it's my understanding that DBRepair is incompatible.
I have restarted Plex Media Server, reinstalled Plex Media Server, rebooted my NAS, and rebooted my router. Any guidance would be appreciated. My tech knowledge is about a 3 out of 10, so be gentle with me.

Edit: You guys are awesome. It was a DNS issue.
