Team, I'm trying to debug my application using Visual Studio IDE 2017 for Firefox browser and I'm getting the error "Secure Connection Failed" - The connection to localhost:44330 was interuppted while the page was loading. 1) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. 2) Pleace contact the web site owners to inform them of this problem. However, I'm able to debug the application using Edge, IE, Chrome and for Firefox - looks like something is blocking. Tried below troubleshooting tips and none of them seems to work. 1) Deleted cert8 file (about:support) 2) Edited the value - security.tls.version.min 3) Edited the value - security.ssl.enable_ocsp_stapling Any helps would be really useful. Thanks, Prasenna
