RDP Protocol Error 2056

Hi,
Since we migrated to Win10 we had an error when we try to connect to a terminal server. No problem to connect to a standard server with RDP, no problem with Win7. Only terminal servers (win2008r2 or Win2012r2) from Win10.

We use ASG RD 2016. Extra info: no problem if we use mstsc.exe.

Complete error (see attachment):Return code 2056 "The remote computer disconnected the session because of an error in the licensing protocol"

Thanks in advance
