Fiddler Suddenly Unable To Decrypt HTTPS Traffic

At one time, I had Fiddler setup to decrypt HTTPS traffic, and it was working.

After having not used the feature for some time, I found that “something” had caused it to stop working, moreover I was getting the dreaded “Proxy server not responding…” message whenever I would capture traffic.

After a little research and tweaking, I could capture, but only over HTTP. After more fiddling (ha ha) around, I found this post about the Fiddler Certmaker add-on, which has restored the functionality.
