Same situation

Set the date to Saturday, March 8, 2025 so you can connect it to your Wi-Fi network until they fix the problem.

Don't worry, my friend, my device is from 2018 and the same thing happens to me.

Yesterday, Sunday, I encountered this problem after performing a factory reset, as it said that the device was not trustworthy, obviously something went wrong and millions of us are affected.
