I'm trying to publish a web site with a self-created SSL certificate on my own IP. After I added the web site to the IIS and tried to run it, I get this error and I'm unable to start the web site.

Internet Information Services (IIS) Manager - The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)

What can be the reason of that problem?

Another process is using port 80 or port 443 on the computer that is running IIS. By default, IIS uses port 80 as the default TCP port and port 443 for Secure Sockets Layer (SSL).
