After hours of trying I finally got FreeRDP-Webconnect compiled.
I executed the script on a Ubuntu 14.04 LTS machine and compiled.

When I use the default config (with SSL parameters) I get the following Error:
ERROR: EHSServer::EHSServer: EHS not compiled with SSL support. Cannot create HTTPS server.

So I removed SSL from the config so I could atleast test WebConnect.
After removing it, wsgate starts up and I can access the Web Interface.

I set up a Windows Server 2012 R2 VM and connected with my local Microsoft RDP without any issues
The pre-compiled wsgate for Windows also works with with TLS Disabled/Enabled.

But when I try using the Linux Version I keep getting the following Errors:
connected to 192.168.154.131:3389 unexpected pubKeyAuth buffer size: 0 Could not verify public key echo! Authentication failure, check credentials. If credentials are valid, the NTLMSSP implementation may be to blame. Error: protocol security negotiation or connection failure

I have set nonla = true NTLM is disabled on both client and Server.

Any ideas/help?
Thanks in advance!

Originally I’ve opened this issue for Remmina but it seems it’s rather a FreeRDP issue. See: https://github.com/FreeRDP/Remmina/issues/946

After upgrading to Ubuntu 16.04 I cannot connect to the RDP server earlier I could.

In the terminal I get this message when I connect with xFreeRDP:
[12:13:37:823] [16032:16033] [ERROR][com.freerdp.core] — freerdp_set_last_error ERRCONNECT_TLS_CONNECT_FAILED [0x20008]

RDP issues only, freerdp version (xfreerdp --version): version 2.0.0-dev (git n/a) 

The FreeRDP still works fine under Ubuntu 14.04

Trying to connect while using a .rdp file. I am using 2.0.0-dev2 (13be713). I execute the following:

./xfreerdp RDPFILENAME.rdp
I am prompted for my user name, the domain and password. Then:
[10:28:44:386] [8429:8430] [ERROR][com.freerdp.core.gateway.tsg] — tsg_check failure
[10:28:44:388] [8429:8430] [ERROR][com.freerdp.core.nego] — Protocol Security Negotiation Failure

[10:28:44:388] [8429:8430] [ERROR][com.freerdp.core.connection] — Error: protocol security negotiation or connection failure

And in addition to this I get:

==8429==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 112 byte(s) in 1 object(s) allocated from:
#0 0x7f8c943a5602 in malloc (/usr/lib/x86_64-linux-gnu/libasan.so.2+0x98602)
#1 0x7f8c8d89ce77 in CRYPTO_malloc (/lib/x86_64-linux-gnu/libcrypto.so.1.0.0+0x62e77)

SUMMARY: AddressSanitizer: 112 byte(s) leaked in 1 allocation(s).

The negotiation does still fail, but the LeakSanitizer-bit does not happen when I use the xfreerdp included in the Ubuntu repositories (version 2.0.0-dev2 (n/a)).
As I cannot connect and do not own the servers I am connecting to, I am not absolutely sure about the version, but my best guess from their documentation is:
Windows Server® 2012 R2 Standard,
Microsoft Windows Server, Version 6.3 (9600)
x64-based (64-bit)

My system: Lubuntu 16.04, 64-bit, kernel: 4.13.0-36-generic

I cannot disclose all the things in the rdp-file, but here are all the fields:
full address:s: FULL-ADDRESS
gatewayaccesstoken:s: CODE
gatewaycredentialssource:i: NUMBER
gatewayhostname:s: HOSTNAME
