If “error code 100” pops up when you load Apex Legends, there may be a problem. There’s a number of issues that could be at hand when it comes to this error code, but server issues are the main culprit. To solve this, the first thing you should do is to make sure the servers are intact. You can check the server status by heading to Apex’s Twitter account for confirmation. If nothing has been posted concerning the servers in the last hour, the problem is probably on your end.
