Unable to Access Media Via Other Accounts

I recently started using Jellyfin to host my media, but have run into a small problem when creating user accounts. As the description states, when these user accounts (not my administrator account) access Jellyfin, they are able to see all available media, but when clicking to play a title, they aren't able to begin playback. This issue does not apply to the administrator account, which is able to play all media on any client. Obviously, using my admin account has been the temporary solution, but could result in unwanted changes to the server or my personal preferences.

Did you check "Allow remote connections" for these users? In Media Playback, is transcoding allowed?

That doesn't seem to be the problem here. It is checked, but this issue also occurs on the host machine.
