All my containers didn’t want to work any more

Good morning everyone,
I woke up this morning and all my containers didn’t want to work any more. I have 500 or 400 errors. You know where I can search for the solution ?
I did an update to see if this will work again…

Without more information there is not much we can do. I suppose 500 and 400 is not the quantity of the errors but HTTP status codes, right? What do you try to access? What fives you the error?
