[node-rdpjs] INFO: MCS DISCONNECT_PROVIDER_ULTIMATUM

I'm facing this error when i try to connect to server using remote desktop...

CLIENT DATA RECEIVED:{"label":"infos","ip":"server2008r2tes","port":3389,"screen":{"width":1093,"height":900},"domain":"","username":"","password":"","locale":"it-IT"} C:\nodeworkspace\pla…\server\mstsc.js:91 activating rdp connection...

Could be this errore related to "unable to verify the first cerfificate" error?

Thanks in advance

I first found a fork this fixed:

As I understand it, the project is no longer supported? I got the same problem. There is a strong suspicion that "Parsing [MS-RDPBCGR] TS_INFO_PACKET" does not give full information about the connected device, which leads to an error. To connect to windows 7 and server 2008, I lowered the degree of encryption on the node node --tls-min-v1.0 server.js But for newer ways, the connection does not work or gives such an error MCS DISCONNECT_PROVIDER_ULTIMATUM .

Using the example of the same xrdp because you can read the logs there:
