Other Fixes

Both methods mentioned above will be enough to resolve your PC’s connection issues to Diablo 2 servers. However, if you are still getting the same error messages, then one of the first things you should always check is if the servers are down or having issues.

• The reason is that if the servers are down, there will be no way to fix them from your end. For this reason, you will have to wait for the servers to eventually return after Blizzard itself fixes what is causing them.
• You can check if the servers are down by checking the game’s and company’s official social media accounts and looking at sites like the Outage Detector.
• If you find that the servers are down, just sit back, have a snack, or play offline by creating an offline character. Sooner or later the servers will come back and you won’t have any connection errors.
