Doesn t work...

If you already tried that and doesn't work, check their solutions:

Solution1:
You are behind a router and your ports are blocked. Easiest way do avoid this is set your computer as a DMZ zone (demilitarized zone). How to do this depends on your router, google enable DMZ YOUR_ROUTER_NAME. If you can't do that but you know how to unblock ports
If you are in a public network with ports blocked and no access to the router you will have to contact your network administrator and tell him tu unblock the following TCP ports: 1111-1119, 1129, 8001-8009, 8019, 8085, 8086

Solution2:
Redownload launcher
Delete Cache folder from Data directory
Also try deleting launcher_freakz64.exe and wow64.exe and open launcher_freakz.exe - but redownload launcher from here https://www.wow-freakz.com/legion_download
Uncheck read only from DATA folder

Solution3:
Right click on Network from tray icon
Open network & Internet settings
Change adapter options
Right click on Ethernet(/your network device)
Properties
Configure...
Advanced
If you have an option to set the Speed&Duplex setting set it to 100BaseTX Full Duplex. / 1Gbps Full Duplex or max.
If you have an option to set the TCP/UDP Checksum Offload setting (IPv4), may vary in specific naming, disable this setting.

Changing these options will normally cause your connection to reset temporarily. You may also have to restart your system after changing these options to connect to the internet once more

After this, Remove the Temporary Files:
The first step to solving this problem is to delete your entire Cache folder(located in the World of Warcraft directory)
The second step to solving this problem is to delete your temporary data files (located in C:\\\\\\\\\\\\\\\\Windows\\\\\\\\\\\\\\\\Temp) AND open Internet Explorer, press Left ALT button, Tools, Internet Options, General: Browsing history: Delete temporary files.

Log on wow-freakz.com website with your account, and switch realms 3-4 times (MOP>LEGION>LEGION>MOP).

Solution4:
First of all remove temporary files from internet explorer.

1. Type msconfig .. Services. Search for any kind of service who has Unknow Manufacturer . Disable them.
2 . Type msconfig in Run.
2. Services Tab . Look for Net. Tcp. Port Sharing Center ( https://imgur.com/a/wl94R ) . For me it.s running now. But i had it disabled..
3. To enable it do this. write services.msc in Run . (Local) task. Look for Net Tcp Port sharing Center . Change the startup type to automatic. Apply. Then ok.
4. Restart your pc. The old error should disappear. and remplace with a new one like We couldn't log you in with what you just entered. Please try again. (BLZ51900003) . Redownload the launcher.
-Also for windows like 8. 10 . Check in services task. For Intel(R) Content Protection HECI Service. .and Disc Soft Lite Bus Service . 2nd it.s from daemon tools tools lite. That harm your pc. Disable both. Same restart pc. And do the above .
If that don.t really help. That should be the solution. https://us.battle.net/support/en/article/23848


Solution5 //was not tried yet:
If you already disabled your anti-virus software try to temporarily uninstall it. We have seen this error caused by AVG, Avast, McAfee and Norton. Disabling doesn't always work depending on the program and a temp uninstall is the only way.

- If you use Geforce Experience or AMD Evolved also make sure they are disabled near the system's clock.

- Bypass the router to ensure it's not a router port issue.

Still doesn t work... I tried what you told me and i also tried to reinstall the game but still same error...

Connection from server to your IP address seems ok, which means your ports are blocked (from router most likely), read info on what to do here https://forum.wow-freakz.com/WoW-Legion-client-t452441.html about unblocking ports / DMZ router / etc... or maybe even a firewall
