It seems Blizzard have been having some issues with World of Warcraft and the newer WoW Classic with them coming under a DDoS attack. Their countermeasures (well, whatever they've done recently) seem to have blocked Linux players in Wine but there's a fix.

You will be able to load the game and bring up the server list but once you click to join a server, it just doesn't work. If you find this happening to you, changing your networking TTL can help. First, run this command in your terminal to find what your current default is:

sysctl net.ipv4.ip_default_ttl

Make a note of the number it shows in case you need to change it back for whatever reason. As for the actual fix, set it to something different like this:

sudo sysctl -w net.ipv4.ip_default_ttl=128

128 is the default in Windows 10.

What does the command do? It changes your "Time To Live" and that's all. As always though you run such commands at your own risk, just here to provide information that might be helpful.

Another possible solution is to enable IPv6 support in the WoW Login screen options, although that won't work for everyone and depends on your ISP and Router.

While you're not supported by Blizzard playing on Linux, people have enjoyed WoW for many years thanks to Wine. Sometimes there's blips like this but thankfully the workaround does work for myself and a number of others who also tested it.

If you use a game launcher like Lutris, it can run commands or scripts you set before launching a game and after you close it, so it's handy for stuff like this where you might not want a permanent change. If you wish to try it through Lutris using that method, you will need to open the options for it: right click -> Configure -> System Options tab, tick the Show advanced options box at the bottom and then scroll to find this:

I've just setup two tiny little scripts to put TTL up and down again on launch and exit. Here's my "" script as a rough example:

[ "$UID" -eq 0 ] || exec kdesu bash "$0" "$@"
sysctl -w net.ipv4.ip_default_ttl=128

You will likely need to replace kdesu with gksu if you're on a GNOME based desktop, which is what will show an actual prompt to ask for your root password since it's needed to change the TTL. Make sure the script is set as executable too. You can use the same for when the game closes, with a lower number than 128 or whatever you wish to set. This is just an example though, whatever way makes it easier for you.

Hat tip to Jaco.

On some systems to make parmanent setting, like Manjaro or Arch to work, add net.ipv4.ip_default_ttl = 80 to:

Good tip, added!

Thanks a lot for this info! I struggled to get online for hours yesterday. It started to feel like a Linux blocking problem after I tried the wife's Mac and got in no problem. Also, my Windows buddy in town with the same ISP didn't have a problem. Really nice to see this posted this morning. :)

I've added an example working (tested myself) script for those that use Lutris.

Quoting: PatolaIt would be nice if you published the fix for the recent Origin network unavailability too, I lost a lot of time doing this one (and even the Lutris scripts does not automatically use the /noUpdate flag yet).
I would love to be able to cover everything but I'm only one person with limited time and resources, plus not a single email came in about it whereas this was sent in.
Sorry. I didn't want to sound like I was demanding it from you, that's not what I meant, I really thought it would be indeed nice if that happened. Of course if I know the solution I should be the one documenting it and sending the patch to the Lutris script, it's just that I didn't have the time this weekend. My schedule is a mess currently.

Quoting: PieOrCakeI played WoW for over a decade, but thankfully managed to kick the habit before the BfA xpac was released. I've been WoW-free for a couple of years now, and holding steady!

I played it for a 2 week trial thingy years ago and I barely left my room during that time. When the trial expired I decided against buying it for my health lol.

WoW Classic is the best thing ever happened to WoW :) Really enjoying it. WoW kind of died for me with Cataclysm. Though i have played all the expansions until the last one, they were just good for getting the story line and then quiting. Cause the modern WoW imo is just a buttonsmash through the content. Classic is amazingly frustrating yet rewarding :)
