The author sometimes couldn't authenticate when he wanted to open Pokemon GO.

1 The Registered User Name or Password is Incorrect

Most likely, you entered the wrong username or password when registering for the Trainer Club. Also, I originally registered with a Google account or Facebook account instead of the Pokemon Trainer Club account, but I misunderstood and tried many different methods.

2 Wi-Fi and Tethering are Used Together

One of the reasons why Pokemon GO can not be authenticated is that you are using a Pokemon Trainer Club account and you are using Wi-Fi or Dethering in your Internet environment. Also, Wi-Fi problem may cause the problem of Pokemon GO routes not working.

Also, if you use Wi-Fi or dethering at home and log in to Pokemon GO, it may be displayed that you cannot authenticate when you go outside.
