Thanks for your time to help me first~
My site was hosted in ipage.com and works fine through cloudflare.
Recently, I plan to move my site from ipage to a VPS, so I set up the VPS and backup the whole site, updated the A record with the new IP of the VPS in Cloudflare DNS settings. And then went back to upload the backup and installer to the VPS.
But what’s strange is that: I can visit the installer from the new IP from VPS, but in the installation process it says, can’t connect to the database created in my VPS. And then when I checked, it gave me 523 Error.
Could you help me out?
