For anyone with a problem using HTTPS decryption in Fiddler, the following questions must be answered for me to have any chance of helping you.
Q1> What version of Fiddler and Windows are you using?
v5.0.20182.28034 for .NET 4.6.1

.NET 4.7.1 WinNT 10.0.17134.0
Q2> Which HTTPS protocols are enabled (Tools > Fiddler Options > HTTPS > "Protocols" link at the right.
<client>;tls1.0;tls1.1;tls1.2
Q3> Which certificate maker are you using? (Tools > Fiddler Options > HTTPS > click "Certificates Generated By")
