Report Server URL page can't be displayed.

Question

So we attempted to upgrade sql 2012 to sql 2014 for SCCM. Upon doing so this broke reporting services.  My dbadmin reverted back to sql 2012 and now we cant get reporting services at all to work.  The issue started when he went to upgrade sql and
it had an error on the reporting services part because of some ssl cert which I don't think we use since the service urls are all http.  I could never get the https to work the first time.
I am doing all of the below on the sql server itself.
in the reporting services configuration manager web service url section when you click on the report server web service url it goes to a page cant be displayed.  If you go to the report manager url section and click on the report manager site identification
url it does take you to a webpage but says unable to connect to the remote server.
Any one have any ideas?

What you might do is look at the URL reservations.  In order to view what is bound to http.sys you will need to open a command prompt on the server use the following command to view records:  
netsh http show urlacl
If someone isn't correct, you can remove it using the following command, as an
example:
netsh http delete urlacl URL=https://servername:443/reportserver
URLs also get written to the rsreportserver.config file.  So you may need to remove entries there.
I have had to do this for failed SSRS bindings.  When making changes using netsh, do so with extreme care.  In theory, removing all your bindings using reporting services configuration manager and re-adding them is supposed to do this for you,
but i've found out that isn't always the case.  You could always try that first.  It should be noted that in order to complete this step successfully, the report manager URL should be removed first (through the advanced button), then the web service
URL.  When adding it back, the order is reversed, with the web service URL being added first and the report manager URL being added second.
