World of Warcraft Error BLZ51903006 Fix
Normal and classicWorld of Warcraftcan be susceptible to this error. If you are seeing it, there might be connection issues from your side. The first step should be checking our guide to see ifBattle.net/Blizzard is having server issues. Don’t worry if that comes up clean; more troubleshooting options exist.
Now, fully close out theBattle.net Launcherand reset your internet connection to be safe.Now Launch the game from the .exe filewhere you have the game installed instead of using the launcher. This will route your connection slightly differently and might cure your problem straight away.

If not, others have found success by deleting your Blizzard Cache file. You can find it by clicking on the address bar (the section that shows your current folder path by the search bar) in Windows Explorer, and when it lets you type,enter in C:\ProgramData. In ProgramData, look for theBlizzard Entertainmentfolder, and the Blizzard Cache file will be inside.
There are other ways to get to the ProgramData folder, but this method can be done from any currently open folder. If your main hard drive has any other letter designation, just swap the C to that letter.

If this somehow still doesn’t do it, go back into ProgramData andcompletely delete the Battle.net folder. While that sounds a little crazy, it is perfectly fine. The contents will be refreshed the next time you open the Battle.net Launcher. You aren’t deleting anything that won’t simply be replaced. Note this is only your final resort; the second fix should’ve done the trick.
