[Solved] I get the following error when i try to connect to my server over HTML5 Portal "Error: Protocol Security Negotiation Failure"

HL2

Protocol = RDP

UTM = 9.4

Server = 2012 R2

Browser = FF 45.0.1


Any suggestions? Usual RDP connections in local network works perfect!

Edit: Ok, i have found the fault. The RDP Connection on the Server 2012 was wrong configured

    I'm sorry.

    I have only german versions of my Windows installations but the translation of the option is:

    "Allow connections only from computers running Remote Desktop with Network Level Authentication"

    Here a screenshot from Internet
