Original GitHub issue: https://github.com/electerm/electerm/issues/3585

Electerm Version and download file extension(Electerm版本和下载文件后缀)

electerm-1.39.119-win-x64-installer.exe

Platform detail (平台详情)

Microsoft Windows NT 10.0.19045.0 x64

What steps will reproduce the bug?(重新问题的详细步骤)

Trying to connect via RDP to Windows Server 2008 - 2019. (lower than 2022)

After connectiong i get grey screen and message in logs.

While trying to investigate, realized that the node-rdpjs library can cause SSL issues. But I have not been able to figure out why this error occurs. Maybe there is a way to skip certificate validation when connecting?

What should have happened?(期望的结果)

Establishing the connection

Would this happen in other terminal app(是否能够在其他同类软件重现这个问题)

No response

Additional information(其他任何相关信息)

Yes, this fixes the Windows Server 2022 connection error, but with older versions of Windows Server (tested with Windows Server 2016, 2019) the connection does not work.

Seems limited by the rdpjs lib, currently no other rdp lib to use

Is there way to try this one - node-freerdp2 - https://www.npmjs.com/package/node-freerdp2?
It's have an option certIgnore: true

Is there an option to switch to this library? I was able to replace the backend part, but was unable to load the screen on the frontend.

I can see the same error when connecting from Windows 11 to Windows Server 2016 and 2019. I have not tested other Windows Server versions. I tested it with both NLA disabled and enabled.

Is the screenshot from the Credentials Manager in Windows? If yes, I do not see such a record on the client or the server.
