Hi, I am using Kaspersky Security Cloud 21.1.15.500(c) and when I run my visual studio web application (which run on localhost:5001) on self signed SSL not working at all and here is what I configured: 1- added https://localhost:5001/* to exclutions in URL Advisor 2- added https://localhost:5001/* to Trusted URLs 3- added my project folder to exclutions in “Threat and exclutions settings” 4- added [visual studio, msbuild.exe, myAPI.exe ] to trusted applictions in “Threat and exclutions settings” 5- added [localhost,127.0.0.1] to exclutions in “Network settings -> Encrypted connection scanning” 6- enable “Do not decryot SSL connections that use EV cirtifictes” 7- disable “Scan secure traffic in Mozzila appliction” then using firefox as default browser and no luck after all of this. the only way is closing kaspersky to make my applications working. I am struggling on this for 6 days, please can any one help me and explaining what is the problem here
