The subject line captures the error that I am receiving anytime I attempt to open a file stored by DropBox on my PC through the File Explorer. I have tried various media players, VLC, Windows Media Player Legacy, Windows 11 Media Player, 5k Video Player (which plays virtually any extension) - And these are all Mp4 videos, which are compatible with any and every of those players listed.
The strange thing is that this error is intermittent, sometimes the videos load great, other times they provide this error. I have tried it with/without my VPN turned on thinking that perhaps it was an access issue with the VPN IP being active, I use a static IP address so it couldn't be from dynamic IP changing - I'm at a loss.
