Hey there!

So the errors you are seeing means that something is blocking WoW and preventing it from connecting properly.

It's usually a security program or other permission/access issue. I cannot say for sure what might be going on in your case without any information about your system but I do have some steps you can try that may help.

Try doing a power cycle on your system. Turn off all devices including the modem. Wait 60 seconds, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

*If you have any addon managers installed.* They are fine programs but they have the tendency to prevent our troubleshooting steps from working. Please uninstall them and leave them off your system until we have solved the problem.

From here we need to delete the temporary game files that may be corrupted. Your game will rebuild them when you next login but this will remove all installed addons. Please do not reinstall any addons until we know the issue is resolved.

Let's reset the in game user options:
1. Click the blue bnet icon on the bnet app.
2. Choose settings, then game settings.
3. Click the reset in game user options button under the correct game listing.
4. Confirm the changes and close the window.

Try running your system in selective startup mode.

Once that is complete I then would like you to temporarily uninstall (disabling the programs often causes them to clamp down even more) all security software currently on your system and then restart the computer. Test the game. Once you have completed testing I recommend putting some sort of security programs back on.

If none of that helps we need some system information from you via a direct support ticket. Get that to us and we will work with you to figure this out. :)
