Description Mohammed Gritli 2022-08-08 09:30:18 UTC 
SUMMARY
***
KRDC doesn't have a setting to set security negotiation to RDP/NLA/TLS while connecting.
This results in not being able to use the application with some versions of RDP servers.
an option is available in freerdp "/sec:rdp" which overcomes the TLS version issues.

STEPS TO REPRODUCE
1. connecting to any RDP server that doesn't have a compatible TLS version
2. 
3. 

OBSERVED RESULT
the screen closes without any error showing
I was able to troubleshoot the issue via freerdp command which shows:
transport_connect_tls:freerdp_set_last_error_ex ERRCONNECT_TLS_CONNECT_FAILED

EXPECTED RESULT
have the option to set security negotiation in connecting settings.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: Kubuntu 22.04
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3

ADDITIONAL INFORMATION
Option is there in Remmina as well

Does using the extra options field work?

> Does using the extra options field work?

Oh yes, now it works with extra options field.
but I didn't think of trying that, forgot it used freeRDP .
However, I think there should be an easy way to change those options since it's a common issue.

Thank you

This option is very important in my workflow and i have to use freerdp or remmina to get the connection to work. Please consider adding it in future version. (22.08.3 on Gentoo)
