I have 2 servers in my farm (plus, an additional separate DB Server). I use one of the servers as a Central Admin server and the other is a combination WFE and App Server. The search application is on the App Server. The Central Admin server is on a separate but internal network. SharePoint is used within my organization as an intranet.
When I navigate to the Search Administration page on the Central Admin server the "System Status|Administration status" shows the message: "The underlying connection was closed: An unexpected error occurred on a send." The "Search Application Topology" section shows the app servers name with green checks for every component: Admin, Crawler, Content Processing,....
Clicking on the "Crawl Log" link on the left shows the "Sorry, something went wrong" (SSWW) page with the message "An existing connection was forcibly closed by the remote host". In the logs on the Central Admin server, shows the error appearing when a call is made to the HTTPS address of the Search's web service on the App Server. On the Central Admin server, I open IE and plug in the URL for the web service. I receive a message "There is a problem with this website's security certificate."
Just for fun, I change the URL. Rather than use the HTTPS binding, I try the HTTP site's connection, and I receive no error, just information about the SearchAdminWebServiceApplication Service. So the HTTP binding appears to be operational.
So, I have 2 questions:
How do I repair the HTTPS SharePoint Web Service binding (which appears like a certificate issue) to make HTTPS work correctly?
How do I shut HTTPS binding off and tell SharePoint to only use the HTTP binding? Is it as simple as removing the binding for the site?
If you need more information or if this is not clear please let me know and I'll do my best to make it more understandable.
Thanks for reading and thank you in advance.
