Hey! This error pops up when the app can’t load your controller upon start up of the app. I checked on some logs and it looks like we had some cases where the connection the app makes to our servers closed when trying to make the request that failed for you.
Since that’s the first connection we make when the app starts up, it looks like there’s some issue creating that connection. One thing to try would be to try disconnecting from WiFi temporarily and try connecting via cellular to see if that allows you to get in to the app. If that works, we can potentially debug further on what could be preventing the app from connecting while on WiFi.
Let me know if that works for you!
