The beginning of the problem:

 

For months my computer would take about five minutes for HTTPS connections to function. As a result, Skype could not connect during this time and any HTTPS web requests would be stuck in "Establishing Secure Connection" during this time. I finally fixed the issue by removing all the DO_NOT_TRUST_FiddlerRoot certificates that I found in the "Personal" store.

 

Since then, fiddler is unable to decrypt HTTPS requests properly. Instead, Chrome displays a Privacy Error. I have seen other people on this forum with this problem fix the issue by upgrading Fiddler, checking a dll, or trusting the root certificate. On these points:

My Fiddler Web Debugger is v5.0.20182.28034 for .NET 4.6.1 (Running ELEVATED)
I do not understand what DLL I should be looking for in order to ensure that I have the right certificate authority. I have the CertEnroll engine.
In Tools > Options > HTTPS > Action:

  • I have never noticed a change when I choose "Reset All Certificates".
  • "Trust Root Certificate" does not work, the log shoes an error message: "The RFC server is unavailable"
  • I am able to "Export Root Certificate to Desktop" and install these certificates in the "Personal" store, but not "Trusted Certificate authorities".

As far as I can see, the basic problem is a permissions issue:

  • I can't delete a FiddlerRoot certificate (a certificate that I do not believe is the current root) from Trusted Certificate Authorities. (error: RFC server)
  • I cannot install a new root into "Trusted Certificate authorities" (error: store is read only, or did not open properly)

Any ideas on what permissions specifically are neededfor these RFC server error messages to be fixed?

 

Appreciate your help.

Correction: 'The RPC server is unavailable' (not RFC)
