Oh right, Network Level Authentication... You have to change your server setting.
Windows(or super)+R and Run SystemPropertiesRemote.exe
Theres 3 options under Remote Desktop
1) Don't Allow connections to this computer.
2) Allow Connections from computers running any version of Remote Desktop (Less Secure)
3) Allow connections only from computers running Remote Desktop with Network Level Authentication.
Select option 2 to support non-Microsoft remote desktop applications... NLA only works for Windows Vista SP1 or higher versions of Remote Desktop.
Some will claim to support NLA... but like this article, shows that only under certain circumstances that it might work... if its even a legit claim. I'm sure they have the system joined to the domain or something and theres other circumstances that allow the NLA transactions to occur without a problem.
