ERROR 403 ON SUBDOMAIN

aaP_beacadmedia

Hello Team, please I need an URGENT help, I have a web application that needs nodejs to function properly. The project's backend is installed on the main domain (E.g www.xyz.com) and the server is deployed on the subdomain (subdomain.xyz.com). When I visit the subdomain, I get an error 403 whereas I am to get a page . If however I delete the current files in the subdomain, then reload the subdomain, the default nginx page shows up.

Please help me.
N:B; the domain is quickb2c.online and the subdomain in question is waziper.quickb2c.online

Hello, the 403 error is generally that the server received your request and then returned an unreachable result. It is recommended that you check whether the permissions of the subdomain wziper.quickb2c.online are correct.
If the subdomain shows the default nginx, there is no file of your own.
