*****UPDATE: RESOLVED*****
I thought I would take the time out to return to this post in the hope that this information helps someone out, now/in the future...
I recently installed _ProtonVPN_ and, since installing, have not had one disconnect. I have played extensively and thoroughly through instanced story mission content, open world and WvW.
I hope this information helps someone, should they be looking for a fix.
Take care. Happy Christmas and keep safe.
