"Unexpected EOF" Error for Spotify and Core 18

There may be more that wouldn’t work for me, but these are two that I’ve tried installing on Solus 4.1 with no luck. Last I checked, things worked fine on Manjaro(however that may have been weeks ago that I installed Spotify on Manjaro). I’m new to Solus and have no idea if this may be a Solus issue rather than a Snap one. Any help is very much appreciated.

Specifically, when I try running sudo snap install core18 it returns:

error: cannot perform the following tasks:
- Download snap “core18” (1668) from channel “stable” (unexpected EOF)
