Hey, Demon! The 3006 error is a common connection related error. This is why your friends are able to play while it’s giving you this error.
While other games are working, connection is made up of a fairly complex network. These games will have completely different servers and server locations from Diablo III. Even other Blizzard games will have different connection routes from one game to another.
It can help to try some basic troubleshooting, these steps may help address the error:
- Reset the network devices
- Troubleshoot security applications.
- If you have Killer Network and the Killer Network Manager, disabling Bandwidth control under Interface may help resolve this problem.
- If wireless, try a wired connection if possible. If a wired connection is not possible, it may help to try switching between 2.4Ghz to 5Ghz if dualband is supported. Due to stability issues, wireless connections are not officially supported.
An alternative connection or VPN should workaround the issue in the mean time and help narrow down these concerns.
We can take a look at the connection route to see what’s happening with the connection to the Diablo III servers, could you provide a WinMTR test? Run the test until the problem occurs for 5 to 10 minutes. Copy and paste the text file created and paste it between two ~~~ like so:
