After an update, I found that I am not able to connect to local network
machines through RDP.

I have 3 machines, all of them are accesible from a Windows OS without any
issues.

Using remmina or KRDC I instantly get Cannot connect to the "192.168.1.248" RDP
Server.

I've tried disabling NLA on the RDP servers, even though it worked before the
update without any issues.

Connecting to port 3389 using nc works:

nc -zv 192.168.1.248 3389
Connection to 192.168.1.248 3389 port [tcp/ms-wbt-server] succeeded!

Starting remmina from konsole, I get:

Load modules from /usr/lib64/remmina/plugins
Remmina plugin glibsecret (type=Secret) has been registered, but is not yet
initialized/activated. The initialization order is 2000.
The glibsecret secret plugin  has been initialized and it will be your default
secret plugin

So, it seems an update broke something related to libav H.264 codec library.
I added the Packman essential repository and switched to this repo so the
avcodecs are installed. After this operation everything is working fine.

So it means some update broke something that was working before. I only added
the Packman repo after I've noticed this issue.

Please let me know if there is the need to send you the zypper logs. The issue
happened few days ago and I still have the logs.
