Hello, the nginx/apache aapanel installed using the apt command cannot manage the website added using aapanel.
You need to stop it and install nginx using aapanel
Are the latest access records in the log at your time?

Yes, that's access log, what does that mean?

ok kern, I have stopped nginx via SSH and uninstalled nginx via aapanel, and now I have installed it again and the website is normal. Thank you for the help.
