Add SSL to a non-80-port web site

Question

I have a web site that uses a port other than 80. Let's call it http://mysite:999. I need to add SSL to this site, but cannot remove that "999" from the URL, as that's the only way to access the site.

I've searched, and the closest answer I've seen is this:

As that was from 2017, has anything changed, or is that still the preferred method? Or is there a better method?

Answer 1

Hi @Phillips, Keith ,

As per my research, to enable SSL for a non-80-port site and keep the bound port, you need to create an https binding with 999 port and enable SSL in IIS manager as said in the post. It is still the preferred method and the only method as per my knowledge.

Answer 2

One issue - I tried to add a new HTTPS binding for port 999, and got "the specified port is being used by a different binding." IIS won't let me edit the existing binding, either. Is there a way around that?
