How to fix PUBG failed to authenticate from external provider

You are not alone if you are currently getting a failed to authenticate from external provider error in PUBG. The failed to authenticate error is extremely common when PUGB gets a high influx of players. Luckily, you can easily fix the PUBG failed to authenticate error with a few troubleshooting steps. We recommend following the steps below until you find one that works and fixes the problem. 

• Close and restart Steam client
• Verify Steam Files
• Restart PC
• Put Steam into Offline mode and restart

If putting Steam into Offline mode or closing and restarting doesn't work, then you must try verifying Steam Files or restarting your PC. But if the problem persists even after these two steps, the error could be caused by a broader server issue.

If a broader server issue causes the error, then there is not much you can do beyond waiting for the problem to get fixed. You can check to see if there are server issues by visiting a site like Downdetector or the official Twitter account for PUBG. Doing so will allow you to see if PUBG is currently down or if there are any server issues affecting it.

How to close and restart Steam

To use the close and restart Steam client method, you must first hit CRTL+ALT+DELETE and open the Task Manager. After hitting CRTL+ALT+DELETE a list of options will appear, with Task Manager being the last option. Click Task Manager and then find the Steam client under the list of Processes. When you find the Steam Client, right-click it and then click End Task. Make sure to close both Steam Client Service and the Steam Client Bootstrapper or Steam Client 32 bit. Doing so will close Steam and allow you to restart by relaunching it. After relaunching Steam, PUBG should launch as normal.
