Error 3003(1)Category: Technical SupportJanuary-17-2016 5:42 AM PST (9 years ago) Go to Blizzard forum post
I keep getting error code 3003 when trying to log in through the Battle.net client.

If I click on "offline" and start Diablo and log in there it usually take 3-4 attempts before I get in.

I'm using a cable so it's not my WIFI.

I have run a virus scan and Malware bytes, whom didn't find anything.

In "Component Services" I have set "Secondary Log-on" to automatic as someone suggested.

I have deleted the folder "C:\ProgramData\Blizzard Entertainment\Battle.net"

I'm running Windows 10 x64.

What to do?

Hello Skeletor,

You have a very high amount of packet loss since the first hop on the pathping.

- Reset all your network devices (switch them off for couple of minutes and then switch them back on)
- Refresh your DNS by pushing Windows key R at the same time and writing ipconfig /flushdns on the Run window.

Make sure no security program in your computer is blocking your connection. If the problem persists I would recommend contacting your internet provider and passing on the pathping to them. That way they can check what's wrong and help you solve it.
