When trying to open Pokémon Go as usual today, suddenly there is no response and then the message "Unable to authenticate. Please try again" appears. I don't know if there is any good solution.

pokemon go unable to authenticate

It is often heard that when opening Pokémon Go, occasionally there is a situation where authentication or login is not possible. In this article, I will describe the solution to the problem of not being able to log in after validating or changing the model.

Part 1. Reasons Why Pokémon Go Unable to Authenticate

Pokémon Go has been more and more popular in the world. With continued breaking records, it has increasing number of players consistently. More recently, though, many players have reported login issues to get close to the new Pokémon. This can be very frustrating for those who have tried repeatedly without success. Here are some reasons why this might happen:

1 Wrong Registered User Name or Password

It is very likely that the username or password you have registered with Trainer Club is incorrect. Also, the registered account was originally registered with a Google account or Facebook, not the Pokémon Trainer Club, but I misunderstood and tried many times with another method.

2 Use Wi-Fi and Tethering Together

One of the reasons why Pokémon Go cannot be authenticated is that it often happens that you are using the Pokémon Trainer Club account but also using Wi-Fi and designing in the Internet environment.

Also, if you log in to Pokémon Go at home using Wi-Fi or tethering, you may see that you cannot authenticate when you go out.

3 Pokémon Go's Own Glitch

The Pokémon Go app is sometimes maintained, so sometimes I don't open the app. At this time, let's first look at the announcement on the official website. Usually, there should be an announcement on the official website. If so, leave it alone for the time being, wait until the time notified to the official website to open it again, and it will be safe to open it.

4 Restricted Area

Also, if you travel abroad or go on a business trip, unfortunately if you go to a country that does not deliver Pokémon Go, not only will there be no Pokémon around, but you will not be able to open Pokémon Go. To solve the problem, Go to the trick to change the location information.
