Additional Context

No response

The report names Termix 2.6.0 and 2.6.1, a Proxmox LXC installation, and RDP targets on Windows 7, Windows 10, and Linux, but no source file or test. Reproduce the Windows 7 failure and compare it with the working 2.5.0 Docker and Windows 10 cases; done means RDP connections work without connection errors or endless retries.
