HTTPS handshake returned error SEC_E_ALGORITHM_MISMATCH.
Fiddler&#39;s Enabled HTTPS Protocols: [Default] are controlled inside Tools &gt; Options &gt; HTTPS.


Some HTTPS sites are unaccessible when using Fiddler

I was able to fix it by enabling the TLS1.2 protocol which is not enabled by default for outgoing connections (Tools / Fiddler Options.. / HTTPS / click on protocols list)
