The Lord of the Rings Online default terminal output - wine 8.14

Hello,

Since a few days all the applications and games I tested, that uses online
services, have trouble connecting to their servers. This includes:

- Steam;
- Blizzard Battle.net;
- World of Warships;
- The Lords of the Rings Online;
- Dungeons and Dragons Online.
I've not tried any other windows application, yet.

- World of Warships is very slow to start, and sometimes ends up with 'not
connected to the server' in the port, with missing online content. I can play
online matches, though, but finding a match is slower than before. I think the
game tries hard to start and to reconnect.
- Blizzard Battle.net often fails to connect for the login screen. It says
'connecting' for a minute and then shows an blz#### splash screen with buttons
to go 'offline' or exit. It sometimes manages to connect, but then can fails to
load the online content (world of warcraft videos and news feed for instance),
with a message to retry.
- Steam is just being slow to open and to display online content, sometimes
staying at a blank space; It's overall functioning.
- The Lords of the Rings Online and Dungeons and Dragons Online both have
slowdowns when opening their respective launchers, and connecting to the world
servers fails constantly after several retries (20 retries in 1 sec. each).
Sometimes, the launcher display an error message about a socket error.

I attach the terminal output from The Lords of the Rings Online as it's the one
that does the most visible retries at connecting to its server and is
constantly failing.

The issue is present with my compiled wine version (from 8.11 to 8.14), as well
as the Debian wine 8.0~repack-4 package and the winehq-devel 8.14~bookworm-1
package (Those two I tested to be sure it was not my builds that were broken).

I've upgraded to Debian 12 in mid-July. All those applications and games were
working by then, with wine 8.11. I don't know what has changed on my system
since then that has broken everything. There were a few kernel updates and also
updates to those applications (WoWs 12.7, Steam on 1st of August, LOTRO & D&DO
had an in-game shop update, blizzard had an update, etc. but the symptoms seem
common and I doubt they are caused by individual updates.

I also have no more sound from another offline game that worked in July and had
no update as it doesn't connect to internet at all, but I'll leave that sound
issue for later. It may be a kernel/system library update, though.

I have no problem accessing internet from Linux programs including the native
Steam & Discord clients.

My system is Debian 12 Bookworm with 32 GB of RAM.
NVidia RTX 2070 with proprietary driver 535.104.05.

Regards.
