Bug Description

Remmina on Ubuntu 22.04 can't connect to windows server 2008 R2

error:

Could not connect to the RDP server "*******" via TLS. See the DEBUG traces for more information.

Remmina Version: 1.4.25 (git n/a)

i think remmina on ubuntu 22.04 doesn't support TLS 1.0

Our TLS libraries in Ubuntu default to disabling TLS < 1.2 since 20.04, see https://discourse.ubuntu.com/t/default-to-tls-v1-2-in-all-tls-libraries-in-20-04-lts/12464/4

You can enable TLS 1.0 by lowering the security level, see https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level

Does that solve the issue?

The only error i have on debug is:

[12:56:01:917] [2797:2879] [ERROR][com.freerdp.core] - transport_connect_tls:freerdp_set_last_error_ex ERRCONNECT_TLS_CONNECT_FAILED [0x00020008]

yes i tried lovering security level but it's the same.

the issue seems similar to bug #1954970, copied from another report

'2008r2 gateway probably fails with ERRCONNECT_TLS_CONNECT_FAILED since openssl3.0 is not compatible with 2008r2 on tls seclevel 1 anymore'

I just hit this bug and found out that a temporary working workaround is to edit your RDP connection in Remmina, go to the advanced settings tab, then in the negociated security protocol chose RDP security protocol.
