Exchange ECP and EMS not working after reboot

I have an exchange 2013 server which was rebooted today. Since the reboot i cannot get into exchange management shell or ECP. I get the following error in EMS: New-PSSession : [] Connecting to remote server failed with the following
error message : The WinRM client sent a request to an HTTP server and got a response saying the requested HTTP URL was
not available. This is usually returned by a HTTP server that does not support the WS-Management protocol. For more
information, see the about_Remote_Troubleshooting Help topic.
On ECP i get the following:
HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid

I have seen this error occur in earlier versions of Exchange and found it was caused by multiple bindings occuring for the same port. Here's the fix:

Open IIS Manager and go to the default site.
Right-click default site, and then click Edit Bindings.
If a binding exists for HTTP, clear the host name value.
If no binding exists for HTTP, create a new binding that has no host name and a value of All Unassigned for the IP address.
Restart IIS.

Here are what my bindings currently look like for default website:Screen-Shot-2018-01-05-at-4.35.07-PM.png Should i remove both http bindings and create a new one  with a value of all unassigned?
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
Yes. It isn't an exact match to the problem. So make a note of what it says now (in case you have to put things back again) and do that.

Hi Dean,

Owa is working? Outlook works?

The only affected are ECP and EMS?

DeanAuthor Commented:
Hi Valentina. No OWA and Outlook both not working.
Brian, i will try your fix but i am pretty sure i tried this earlier. It didn't work.
DeanAuthor Commented:
Brian, i removed the HTTP and HTTPS bindings and recreated them. That unfortunately did not work.

Are all the Exchange services up? ... I have a theory based on the other solution. I've seen port conflicts cause problems like this with other programs. Stop web services and anything else that might use port 80. Then start the Exchange services.

Other than that, please share any event logs related to Exchange services.

Brian, all services are up. What i am seeing though is another website using port 80. Although i have stopped the website completely it has not made any difference.
This is what i get from ECP:

I am also getting this as an event. Seems to be related to certificates. Although i cant connect to ECP or EMS to check.

DeanAuthor Commented:
Brian, Valentina. Thank you for your help. I found the problem. A while ago we had WSUS running on this server as well. It was uninstalled. Reinstalling it but keeping inactive solved the issue. Thank you very much for your time and effort none the less.
Brian BEE Topic Advisor, Independant Technology ProfessionalCommented:
All good information thanks.
What you might have to do is identify whatever other service is using port 80, set the service to manual start and then reboot.
