Unable to connect to Battle.net or login to any Blizzard game

Support Technical Support
1

Error code on Battle.net desktop app is BLZBNTBGS80000011.
Error code on WoW login is BLZ51901016.

My internet is normal. I have even tried resetting modem/router, restart PC, called up ISP to reset modem IP. Is this related to the recent DDoS that restricts player access from certain region? I am from Vietnam and play in Americas/Oceania region if that matters.

Hey there!

Thanks for reaching out to report this. There weren’t any known outages at the time you mentioned, so if you’re still unable to connect, be sure try these troubleshooting steps to fix many common connection issues.

If still unable to connect, let’s go ahead and have you run a ‘WinMTR’ network test while the problem occurs so that we can further investigate potential network-related issues between your computer and the game server. Here are the instructions:

  1. Download the tool from this page.
  2. Enter the game IP into the “host” field. The IP address for our games are listed on the WinMTR instructions page.
  3. Start the test and try to log in as normal. Ensure the error happens while the WinMTR tool is running.
  4. After recording the problem data for 3-5 minutes, click Stop then “export text” and save the WinMTR file in an easy to find location (such as Desktop).
  5. Once you have that made, open the file. You’ll need to copy and paste the contents of the Text document into the post, and put four Tilde (~) marks above the WinMTR. It’ll look like this:
WinMTR goes here

If you have issues pasting here, please use Pastebin and post the link (ex: Pastebin (dot) com/123456).

Sorry I was away for work.

I went through the steps in the troubleshooting page, nothing works. I could not even log into the battle.net page for authentication to log into WoW forum. I can only login when I use VPN, but playing WoW with VPN connectivity is so laggy it’s not going to be an option for me.

I even called up the ISP just now and asked if they knew anything, but all they were saying is the access is being blocked from your end, not the ISP as they did not do anything. Please check again.

I have the WinMTR running for Oceania IP 103.4.115.248 with the VPN turned off as follows:

Hey Meatonwheels,

Thanks so much for taking the time to provide an update on this issue. If you can connect while using the VPN (or any alternate connection for that matter), that does confirm that something specific to your primary home network is preventing the connection. If this is the case we can only recommend contacting your service provider again for assistance isolating and resolving the issue with the home network. They might need to adjust specific security/firewall settings on your modem or temporarily replace the device to narrow it down further.

Note that you can request to speak with a “level 2 or level 3 technician” when contacting the ISP, as the front-line representatives typically only have access to basic diagnostics and troubleshooting tools.

Thanks again for your time and for giving me the opportunity to help you out with this. I hope that you have a great rest of your day!
