Hello Team,

We have a WCF service that is hosted at the production server as well as my local machine, Previously I was able to communicate my local WCF service through our Web application(MVC) over the net.tcp as well as the http, but after the installing the update of KB4565627 (CVE-2020-1147) I am not able to communicate and getting the below errors. I have uninstalled the update and tried to communicate again then successfully able to connect the WCF service.

Could you plz help me to resolve the WCF connection issue along with the security update.

Following errors while communicating WCF through Web Application(MVC) :
Through net.tcp - There was no endpoint listening at net.tcp://localhost.company.com/WCFHost/Service1.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details

Through HTTP - There was no endpoint listening at http://localhost.company.com/WCFHost/Service1.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details


Please find the attached files for the reference.
