Oracle Instance has been stopped for no reason [closed]

I have free Oracle Cloud always free instance. I was not able to connect to it by ssh and it looks like it was stopped.

I cannot re-run it. I get:

Unable to start instance: Instance ocid1.instance.oc1.eu-frankfurt-1.antheljscauatxycmb7qvp36l6jmfffvhfjqspjo6zz3xzbjletwexs7fvsa is disabled and will not accept any action requests. Please contact customer support to reenable.

Customer support doesn't work. Any idea what to do and why it was stopped ?

Solution 1:

Is that an ampere A1 flex instance that was stopped? are you within the initial 30 days free trail or it got expired?
