Problem description
After a certificate is installed on an Internet Information Services (IIS) server, a 404 error is returned when I access resources.
Causes
The following list describes some possible causes:
- The HTTP website is different from the HTTPS website.
- Websites are incorrectly configured.
Solutions
After the certificate is installed, you can access resources over HTTP. However, you fail to access resources over HTTPS, and a 404 error is returned. If you have installed a certificate on the IIS server and port 443 is enabled for the firewall, address this issue based on the following description:
- Different website root directories can be configured for the HTTP and HTTPS services. On the IIS server, check the website associated with port 443 and check whether the associated website is the same as the website associated with port 80 of the HTTP service.
- When you check the website associated with a port, you also need to check the IP address and hostname of the website.
