Hi there @pamh5, I hope you're doing well, it's a pleasure for me to welcome you to the Fitbit Community. 
Thanks for bringing this to my attention, at this moment some people have reported inconveniences when trying to log in to the Fitbit app. In this case I would like to ask you to check if you're able to log in to your online Dashboard with your current credentials. If you're not, please restart your password and then try to log in. Once you're able to log in to the online Dashboard, please try to log in to the app.
If you're still unable to log in to the Fitbit app, please force-close it by double tapping the home button on your phone and swiping it up. If this doesn't seem to work, restart your phone and try to log in again.
I hope this can be helpful, give it a try and keep me posted in case you need anything else.

Hello @nomz, thanks for joining the conversation, it's great to have you on board the Fitbit Community.
Thanks for letting us know about the steps you've performed in order to try to resolve your issue. Our engineers are aware of the problem and are working to resolve it as quickly as possible. In the meantime, please make sure you have updated the Fitbit app to the latest version and restart your phone, then try to log in again. Other thing that has been proven successful for some people is turning off the WiFi on your phone, then try to log in using your data. Once logged in, enable WiFi again.
I'm sorry for any inconvenience this situation has caused. We appreciate your patience and look forward to getting you back on track. If there's anything else I can do for you, please feel free to reply.

Hello @nomz, thanks for taking the time to reply, I hope you're having a great day.
In this case I would like to suggest you to update the Fitbit app and try to log in again. If you're still getting the same error message, turn off WiFi on your phone and try to log in. Once logged in, turn on WiFi again.
I hope this can be helpful, give it a try and let me know the outcome.
