Steps to reproduce
- Install Fiddler on latest Win10.
- Enable HTTPS decryption mode inside Tools > Fiddler Options > HTTPS.
- Trust the Fiddler certificate.
- Attempt to load any server that sends a HSTS header.
OBSERVE: Traffic works briefly. After a few seconds, all requests fail. Reopening browser doesn’t help. Clearing cache and restarting from step #4 works briefly.
Bug reported to @thejohnjansen and may already be tracked internally, but external users are hitting this.
HSTS shouldn’t cause failures of this nature. Sites should load properly with and without Fiddler running.
