If you’ve just opened your Pokémon GO app and see an error message, you’re not alone – the app is down for many players, with no word from Niantic. After announcing a collaboration with music artist Ed Sheeran, players who tried to open the app were unable to access the popular mobile app.

Upon opening the app, players simply received a simple “Login Failed” message. While this might be an expected event during a big event, like, say, Pokémon GO Fest, the shutdown seemed pretty hit and miss. Tuesdays are the game’s Spotlight Hour, where a Pokémon is featured, often having a unique appearance or set of moves. This week’s Spotlight Hour Pokémon is Turtwig, a Grass-type Pokémon that first appeared in Pokémon Diamond and Pearl. Players were eager to get a special Turtwig with a hat in the hopes of transferring it to Pokémon Brilliant Diamond and Shining Pearl, but anyone trying to catch one now is out of luck.

As of this writing, there has been no word from the game’s official Twitter account. However, game developer Niantic posted the following tweet in recognition of the game’s discontinuation:

It’s unclear when the game’s servers will be up and running again, or if Spotlight Hour players will be able to catch the Turtwigs they were promised during today’s Spotlight Hour. Niantic generally compensates players who have been inconvenienced by downtime or server issues, so it’s safe to assume that anyone who missed out on content will be able to access it again later.
