As it turns out, there are several a couple of different causes that will contribute to the apparition of this particular error code with Apex Legends:

Method 1: Checking for EA Server Issues

Before you try any of the potential fixes below, you should ensure that the problem is not beyond our control. As some other affected users have reported, this problem can also occur due to some kind of server issues that are currently plaguing the EA servers. Because of this, you should start this troubleshooting guide by checking services like DownDetector or IsTheServiceDown to see if other Apex players are currently encountering the same 100 error code. In case EA is currently experiencing problems with their servers, one of the 2 directories above should present you with enough evidence that the game is currently in the middle of a server problem. If this scenario is applicable, the only thing you can do is wait for the problem to be fixed by Respawn (the developer of Apex Legends). On the other hand, if you discover no potential server problems, move down to the next potential fix below.

Method 2: Using Google’s DNS

According to the vast majority of users who managed to resolve the error code 100 in Apex Legends, this problem is most likely a DNS (Domain Name System) issue. The widely affected fix, in this case, is to complete the migration to a more stable DNS (most commonly the DNS provided by Google). However, since this issue is multiplatform (occurs on Xbox One, Playstation 4, and PC), the steps of completing the move to a Google DNS range will be different depending on the platform where you’re encountering the error code 10 on. Because of this, we’ve created 3 separate guides detailing how to do this on each platform. Follow one of the guide below (the one applicable to your platform of choice) to complete the migration to Google DNS:

A. Changing to Google DNS on PC

B. Changing to Google DNS on Playstation 4

C. Changing to Google DNS on Xbox One
