A question about installation

ColorStars

After I filled out the database information, click on the installation and wait for a few minutes to prompt me with an error message.

Something went wrong: <html>
 <head><title>502 Bad Gateway</title></head>
 <body>
 <center><h1>502 Bad Gateway</h1></center>
 <hr><center>nginx</center>

How can I solve this problem?🙂

ColorStars sounds like your nginx configuration doesn't have a proxy to php. You need to set up your server correctly so that it can serve php files too.

luceos Other services are working fine, Nginx configuration is correct, I changed to Apache and prompted this problem.🙁

When I visit the homepage again, I am prompted to enter the password for the database, but I am prompted again with a question.
