hi,
we have paid version of hamachi and some users experiencing the same when using RDP over hamachi.
once they connect to RDP hamachi goes south and can't ping the server, rdp stalls or becomes very slow.
personally I don't experience the same. very good. They have upgraded to win10 1909 which I've been using since Nov 19 so fingers crossed.
n.b. once they installed 1909 updated hamachi had to be reinstalled.
