Games running under Wine are unable to reach auth servers

What do you mean you do not have a firewall? If you use debian, there is a firewall active by default.

Yes, iptables is active, but if you'll scroll up just a bit you'll see the output of iptables -L, which shows no firewall rules in effect, so the firewall is wide open.

This is not a firewall issue.

Wine is not running as root.

I'll get a browser running under wine tonight, and see if I can browse https sites.

Have you tried the Lutris + winetricks suggestion I mentioned earlier?

Was out of town all weekend, so haven't touched that PC since Friday. I'll play with it tonight, and see how it goes.

Yes you are right about firewall rules.

"The default Debian installation comes with the program iptables(8), configured to allow all traffic."

And what about the DEBUG flags? do you see interesting errors?

It would look more like a HW network card thing since it works on your laptop but not your desktop.

According to this https://wiki.debian.org/iptables iptables have been replaced with nftables starting in Buster, so the old iptables could be configured to allow all traffic with the idea that nftables would handle policy. I'm not sure how accurate that wiki page is, I'm on a fully-updated Buster install that is still using iptables. My iptables config file also has over 30 lines where as the OP has practically nothing in his, so it (nftables) might be something to check out.
I'd be willing to bet it's a WINE issue though per my previous post, it's something that comes up a lot on the Lutris forums.

Or maybe iptables was cleared because the transition to nftables will take some time.

It seems like a defect that debian does not block incoming requests by default with its firewall. But many distributions run without a firewall so maybe it is fine.
