Major problem - Broken

I love the app, I use it everyday. The major problem with this app is occasionally I get this message:

It usually only lasts an hour or two, but today and yesterday it has been persistent. I have not been able to use the app for 12+ hours. For reference I am currently in India and configured learning Hindi through English. I’ve tried restarting the browser, reloading the page a thousand times. Please help. Thank you.
