All of my websites suddenly went down when I started to make changes within my theme

Hi everyone. I tried many things including restarting MySQL and the websites but none of them worked. I tried to connect via PHPMyAdmin but its not working either. Then I tried to create a new website but still, it didn’t work. I’m not sure but I think there might be a problem with Docker. I need your advice and if anyone could help I would really be grateful.

Thanks,

Ali

I don’t know if it could be related, but this also happened to me, moments ago.

I can access vía SSH, and everything seems fine inside terminal, but in browser, only get an ERR_CONNECTION_TIMED_OUT. I’m on EE 4.0.17.
