From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

PC A and B are running Fedora 41, both on the same local network. I used to be able to use KRDC to remote desktop from PC A to B. After letting both PCs update a couple weeks ago, it's no longer working. When I try, I get the username and password prompt. But after entering, I get a "Could not connect to server" error in KRDC. I get the following errors in the terminal:

KRDC: Starting RDP session

Unfortunately I don't know what update broke it. I just hit 'update all' and walked away. Thanks for any help. Also open to suggestions on any better remote desktop programs.

Disable SSL/TLS and try again.
