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? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to remmina in Ubuntu. https://bugs.launchpad.net/bugs/1968522 Title: Remmina can't connect to windows 2008 R2 Status in remmina package in Ubuntu: New 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.
