I am using aws lightsail instance.
have to upgrade php7.4, so I move my site from one instance to another instance.
everything is the same, ip address, host provider…
The only change i have to make is to detach ip from old instance, attach the same ip to new instance. after that, it shows server down when visiting site.
Do I need to reconfigure my cloudflare ? Or just wait for up 24 hours ?
