Imports to UE4 no longer working

I've previously used mixamo animations on several projects, today I needed a quick pose and suddenly nothing is working. I uploaded a character, picked an animation and downloaded it both with and without skin. Importing without skin just gives me an error about "no geometry information" and importing with a skin, just gives me a copy of the character I just exported without any animation file at all. Thinking it was an issue with my character, I chose one of the default characters, chose an animation and downloaded it. I imported that new mixamo character into Unreal and all I got was the character. No animation file at all.

I'm receiving this error in UE4 when I try to import an animation without skin:

FBXImport: Warning: No smoothing group information was found in this FBX scene.  Please make sure to enable the 'Export Smoothing Groups' option in the FBX Exporter plug-in before exporting the file.  Even for tools that don't support smoothing groups, the FBX Exporter will generate appropriate smoothing data at export-time so that correct vertex normals can
 be inferred while importing. 
FBXImport: Warning: Could not find the bind pose.  It will use time 0 as bind pose. 
FBXImport: Error: There is no geometry information in mesh 
FBXImport: Warning: Get Import Data has failed. 
FBXImport: Error: Import faile

I've tried importing an animation that I previously downloaded from Mixamo and was able to do so without issue.
