Ram Preview not playing through remote desktop

So given the current circumstances i am working from home remotley loging into my machine at work through VPN and using remote desktop. The amount and size of files we work with i cant really transfer to my local machine, its just not practucal and my home machine is also not powerfull enough for the work i need to do.We were using Team viewer however this was giving bad audio playback and i regulary need to hear the audio as well as various other issues with Team viewer. 

So the VPN route (Forti Client Vpn) has been much better apart from one thing.

Ram previews don't always work, they will work for a time after a reset however they will usually stop working meaning i regularly need to restart my system to use them to get them working. The Preview will cache the files as if its working then when complete it just does nothing, no error, nothing.  The bar is green showing the frames are now chached, i can scrub through fine and smooth however i cannot play it back in realtime to check timing leaving me to guess the timing / see it on a render or restart my machine.   However they seam fine through team viewer but i havn't tested this as much.

System: Inel Core i9-7900X CPU @ 3.3Ghz

Ram: 128GB

Card: Nvidia Quadro RTX5000

Any Suggestions?
