Pokemon Go can be prone to the odd connectivity issue from time to time that can impede a player’s ability to enjoy the game. So, this is how players can solve the common ‘Unable to Authenticate’ error message in Pokemon Go.

As is the case with any live service game, players have to rely on an internet connection to be able to play and enjoy the title. Sometimes technical mishaps with connections can prove to be a bit finicky, making for an unstable and frustrating experience.

One of the most common problems stemming from connection issues is the ‘Unable to Authenticate’ message. Our handy guide will give you step-by-step instructions on how to easily fix this error message and get you back outside flourishing in Pokemon Go.

What causes the ‘Unable to Authenticate’ error message in Pokemon Go?

As explained earlier, the ‘Unable to Authenticate’ error appears when there’s trouble with one’s internet connection and stability in Pokemon Go.

However, the message could also appear as a result of Pokemon Go developer, Niantic. Sometimes, Niantic’s servers may temporarily go down, in which case players will simply have to wait until any server issues are resolved.

Niantic Help
Niantic, the Pokemon Go developer, usually updates its social media accounts about server issues.

Here are some ways players can check the status of Niantic’s servers whenever they go down:

  1. You can follow and check Niantic’s official support account on Twitter: Niantic Support.
  2. If no information is present on Niantic Support, searching Twitter and other social media platforms for terms like ‘Pokemon Go servers’ is a great way to see if other players are experiencing similar problems.
  3. Using internet detection websites such as DownDetector or ServicesDown is a great way to quickly see if Pokemon Go has had any recent server issues.

With these three methods, you should be able to find information about Niantic’s servers that could be causing the ‘Unable to Authenticate’ error.
