Even when a game is perfect regarding its source code, it can still run into server-side errors. Anticipated content releases and similar rollouts cause huge influxes in player numbers and trigger server-related errors like DELTA 01.

The DELTA-01 error occurs when there’s a connection timeout between your device and the XDefiant servers. In simpler terms, the game tries to talk to the server but doesn’t receive a response within the expected timeframe.

More often than not, this will be caused by issues on the server side rather than your internet connection, meaning a solution is most likely on the developer or publisher and not the end user.

The best way to fix the DELTA 01 error in XDefiant is to restart your router. Before resetting your modem, you should check XDefiant’s server status. If the servers are down, your only option will be to wait for them to come back online. When they’re online, however, you can try the following alternative fixes for XDefiant’s DELTA 01 error.

  • Change your DNS addresses. Switch your current DNS settings to a new one since a DNS server outage can cause in-game errors related to connectivity. 
  • Try a different internet connection. The quickest way to do this will be through using your phone’s hotspot feature.
  • Call your ISP to learn about potential local outages. Your ISP could be having local maintenance in your area. They can also run more thorough diagnostics on your network and potentially help you fix internet problems.

If none of these solutions work for you, you may want to try upgrading your drivers, resetting your Router and Modem connection, or simply just being patient.

Popular launches like XDefiant will always run into some server issues, so the best course of action in these events is to remain calm. Maybe try setting up a new loadout or getting your gear in order before you’re able to head out into the battlefield!
