Did you check your clock or try to change the api server? You could also try https://bitshares.org/wallet

I have changed it several times, I downloaded the app and the same, the same message.

If that error is consistent then most likely there's an issue with your clock.

You were right, there was a problem with the configuration of my watch. Thank you.

I am having trouble with the same phenomenon. Please let me know in detail
